Putting each NFL week to its max
A beautiful part of stats-based
predictions is being able to directly point at certain stats'
strengths and weaknesses. We put this knowledge to use in our season
betting strategy by rating each NFL week as one of the following:
Cold, Cool, Neutral, Warm, or Hot. This allows our members to really
take advantage of our statistics when they get hot, and to ease off
the gas when they cool down.

If you search around on the net
looking for sports betting advice, you will read a lot of articles
where handicappers slam the notion that you can accurately predict
trends in the NFL and adjust your bets accordingly for max profit.
For the most part they have it right. Using a progressive betting
strategy over a flat betting strategy can lose you a lot of money in
the long run. This is true because most people aren't using accurate
stats. Its that simple. If you have accurate stats you should
absolutely use a progressive betting strategy, and at ITN we have
the stats and definitely put them to use.

Spreads, over/under totals, parlays and more
Much like being in a casino, there are
many ways to make a wager. Vegas has made it as easy as possible for
people to gamble on sporting events, creating parlays, teasers and
much more. Outside of that, there is always friendly wagering being
done between friends, neighbors, office pools or just about anywhere
people associate with each other. For our example, we stick to some
of the most common wagers you can make with sports books and
casinos.

You'll notice that none of the bet
types change the overall number of bets you will be making each
week. ML, AS, and O/U are the base of our betting strategy, and many
of our stats are created with them specifically in mind, so they do
not have any change associated with them. Only parlays and teasers
have any effect on our betting strategy, dropping the BBP. Parlays
drop since they have a much lower probability of being correct, and
teasers drop since you are getting lower odds for your bet.

Your entire season betting strategy in one table
The idea is to take all of the
information from above and put into one piece of data that is easy
to read and understand, which is what we have done with our season
betting table. The table you see below is a typical one members
could have used in 2007. Remember we are using a moderate betting
strategy in this example, which has a starting BBP of 3%. From there
we adjust for how hot or cold we expect each week to be. Our betting
strategy starts generic, looking at the overall philosophy first,
and becomes more specific as we progress through the strategy,
looking at the season, then the week, the pick itself, and finally
to the exact bet to make.

BBP: Base Bet Percentage | NOB: Number of Bets
There is no more guesswork at the
start of each week anymore. Now you will be able to look and know
what your starting bet percentage will be and also know the types
and number of bets you will be making. Having this all laid out
before the season starts allows you to focus on the more fun and
very important process of making your picks!
The table is broken down into 4
stages, which you can see by the highlighting. Weeks 1-3 are a
stage, followed by 4-9, 10-14, and at last 15-17. The stages mark
when you should recalculate your bankroll. Some of you will feel
comfortable recalculating your bankroll at the end of each week. For
example if you start the season with $1000 and win $100 in week one,
you calculate your week 2 BBP off of your new total of $1100.
Another strategy people employ is to wait several weeks before
adjusting their bankroll to allow the law of averages to take
effect. This way if you have an overly poor start to an early week
you aren't punishing your strategy and making it tough to recover.
For example, say in week 1 you lost $200, leaving your bankroll at
$800. If you now use that amount in week 2, even if you have a very
successful week it is unlikely you will recover your losses from
week 1. So instead of adjusting at the end of each week, your
bankroll will be $1000 for weeks 1-3 regardless of how you actually
perform from week to week. Then starting in week 4 you would adjust
your bankroll amount according to how you performed in the opening 3
weeks. So if you had won $150 in week 1, lost $75 in week 2, and won
$35 in week 3, your bankroll for weeks 4-9 would now be $1110.

Predictions begin with the rankings
Our rankings were designed with one
and only one intent in mind: How likely is it that a team will win
future games, with the next game being played the most important
future game. We didn't try to make the rankings reflect whether or
not teams pounced their opponents. We knew that if the rankings
focused solely on winning, how easy of a time a team had winning
would show up anyway.
With this intent in mind we designed a
NFL team ranking system that you simply cannot find anywhere else,
even in Vegas. Knowing that one ranking couldn't possibly tell
enough of the picture to make accurate NFL picks we created two
separate rankings. The first is Win Grade, which focuses on how
solid a team's fundamental play is and how well a team transfers
those fundamentals into winning. Our second NFL ranking is Real
Points, which only cares about the quality of opponents you defeat.
The two rankings push and pull off one another keeping the
prediction system in a nice balance.
For our example we randomly chose a
week from 2007, and week 16 ended up being our lucky winner. Here
are the rankings for NFL week 16, 2007.

Football is a game of matchups
As much as we love Win Grade, Real
Points, and their unification into the ITN Combined Ranking, they
all have their limits. Each NFL game and NFL team are just too
unique to properly analyze using only a ranking system. You have to
look at how well the two teams match up against one another. The
rankings do a great job getting us started on making accurate picks
by not only putting the teams in a reasonable order, but they also
add another unique element.
We didn't come up with Inside the
Numbers as our company name just because it sounded catchy. It
reflected how we view each matchup. The numbers and statistics that
create our ranking system were carefully chosen to avoid redundancy
and accurately express the capability of a team as a unit. Knowing
this we can then look at matchups that were left out of the rankings
but still have an important effect on the outcome of games and
determine whether or not there is enough of a mismatch to overturn
the initial analysis of the rankings.
In a typical matchup analysis we check
the 'health' of our ranking systems and can see if a team is
overrated or underrated, and also see if a team is over playing its
abilities or is under performing for its talent level. We look at
numerous combinations of matchups, and can tell if Cleveland's
passing attack will create enough of a mismatch at home to defeat
Pittsburgh, or if Chicago's capability of creating turnovers and
experience from playing a tough schedule will turn the tide for them
on the road at the Metrodome.
We make use of any stat that improves
the accuracy of our NFL predictions, and classifying each prediction
type definitely helps make winning bets. Here is a list of some of
our common and not so common prediction types.

The beauty of a betting table
Once the rankings have been compiled,
and every matchup in an NFL week analyzed, we can put all of our
predictions into one very informative table. We use data from our
prediction types to determine exactly how probable and profitable
each prediction is likely to be.

Choosing your bets
The betting table from the previous
section is sorted by Expected Value, but be careful in using EV to
determine which bets you will actually be making. Often bets with a
high EV will have a lower probability of being correct each week,
and although they offer higher profits they can also bring some
pretty big swings to your bankroll. So if you have a tighter
bankroll, use probability as the major factor for choosing which
bets to actually go with. Of course, you should always strive to
pick games that have a good probability and still have a positive
EV.
We want to note here how important it
is to have at least 2 different sportsbooks to bet with. No, its not
just cause we want to advertise them to you. Look at the top two
bets by EV in the betting table above. Each one looks to be a very
profitable bet, and you should be taking advantage of them. The only
problem is, you can't make both of those bets with the same
sportsbook! They won't allow you to bet on the money line and the
spread of the same game. So in order to fully take advantage, you
are going to need more than one sportsbook. Having more than one
sportsbook also allows you to shop around some for better odds,
which can be a nice little boost to your profits over the course of
the season. If you are looking for quality and reliable sportsbooks
to do your sports betting, we recommend
Bodog Sportsbook and
Bookmaker.com.

Victory never tasted so green
So how did NFL week 16, 2007 turn out
for us? We put are betting strategy to use, looking at the
guidelines for week 16 in our season betting table. The table showed
6-8 bets, so we went right in the middle and chose 7 bets to make.
We decided to keep things random for our example and chose to flip a
coin to decide between using EV or probability to choose our picks.
EV won the flip, so in the table below you will see the 7 bets we
chose to make based on EV from NFL week 16's betting table. Going
back to the season table we had a week BBP of 4% and then adjusted
each bet for its prediction type to arrive at our final BBP. For
simplicity sake we kept our bankroll at $1000.

Looking at the total amount wagered
(bottom right corner of the table above) is a reminder as to why a
lot of handicappers recommend a flat bet percentage. We end up
wagering $330 this week, which is almost exactly a third of our
bankroll. We cannot stress enough that if you do not have accurate
stats things can downhill very quickly.

Winnings: $418.36 | Wagered:
$330.00 | Profit: $88.36
Despite going only 4-3 for the week,
we netted a nice profit of $88.36. If you are not impressed, you
should be. If you kept your bankroll amount at $1000 for 17 weeks
and matched that rate of profit, you would end up winning $1502.12,
which is over 150% profit for just one season.
