When an NFL team takes the field on offense, their
goal is simple: gain enough yards on each play as to set up an eventual
1st down, thereby moving the chains and starting the whole process over
again, until either a field-goal, or preferably a touch-down, is put up
on the scoreboard.
First-downs can be achieved in many different ways of course;
either through the air, or on the ground; via the big-play, or by using
a more conservative approach that involves more short-yardage
conversions in 3rd-down situations.
Regardless of whether a team is built around speedy Pro-Bowl
receivers that shred an opponents defense for long gains or they take a
more traditional route, involving up-the-middle 'smash-mouth' runs with
a mix of short-yardage pass attempts thrown in for good measure--all
coaching staffs will use the players they have on the field and their
accompanying skill sets in the best possible manner to get that next
first down, or score.
The important question for those of us looking to beat the Vegas
Point spread is: are there certain styles of offense that in the right
situations, cover the spread at a higher rate than others?
The answer is yes and this article will briefly explore one style
of offense that has produced some very good results against the spread
over the past 7 years when a certain statistical bench-mark is achieved.
The particular style of offense I am talking about involves teams that produce a high percentage of big pass play yardage as part of their overall yardage gained by throwing the football.
My official label for this stat is BPY%F (Big Pass Yardage
Percentage For) and it is a measurement of the percentage of total team
passing yards that were gained from passing plays of 20 or more yards.
Dallas led the league in this category in 2007. 42.5% of the
Cowboys passing yardage for the season came on plays of >= 20 yards.
Green Bay and San Diego rounded out the top 3. The league average for
BPY%F has typically been around 40% in most years over the past decade,
but this fell to 37.5% in 2007.
It was actually a good year versus the spread for teams that rely
on the deep ball: The top 8 teams in the league for BPY%F were a
combined 75-45 ATS and none of the 8 had an ATS record under .500.
Conversely, the bottom 8, led by Baltimore's brutal pass attack (they
had a BPY%F of only 25.5%) were a dismal 50-74 ATS.
These interesting results have not played out in a consistent
manner over the past 7 years; however, and in some years, teams with a
high BPY%F have only been mediocre against the number overall while
those at the bottom end of the scale have been closer to .500 ATS.
When we look at teams entering a game with an extremely high BPY%F (greater than 50%); though, a consistent pattern does begin to emerge.
Since 2001--which is when I began to track BPY--teams have been an
excellent 145-119 (54.9%) ATS when entering a game with a BPY%F of
greater than 50% on the season.
Teams that have this large a percentage of big pass play yards are normally only seen in the first 6-7 weeks of the season,
before a mounting number of pass attempts begin to reduce BPY%F to a
more normal level, league wide. That's not to say that some teams have
not carried a 50% level all the way to season's end (Philadelphia from
2006 is a good example, they had a BPY%F well over 50 at the end of
that season) only that, this situation does predominantly play on teams
that are extremely efficient with the deep-pass right out of the gate.
What we have here is good so far, but, there is one more primary
condition that needs to be added to this situation before things really
begin to take shape and it involves how 'game-ready' the opponent of our focus team happens to be, at this early stage of the season.
Here is the meat of this situation: I have found that teams with a Big Pass Yardage Percentage > 50%, playing a team with a Play Book Execution Penalty per-game average against (PBEPA) of 1.3 or greater are a very strong 56-20 (73.7%) ATS since 2001, for a profit of $3,400.00 when wagering $110 to win back $100.
What are Play Book Execution penalties you might be ready to
ask? For those who have not read my NFL Game Sheets Guide, I categorize
penalties under a total of 6 different headings and this particular
category involves calls such as: Illegal Procedures, Formations,
Shifts, Motion, Participation, Snaps and Substitutions; Intentional
Grounding; Delay of Game; 12 Men on the Field; Ineligible Receivers,
and so on--essentially those flags generated by the break-down of
play-calls, mostly on offense. The league average for PBEP's is
normally around 0.7 calls per game (on each team).
It's a category of penalties that act as a good yardstick for
measuring the quality of a team's coaching staff and also provides an
indication if players are being used in schemes where they are
comfortable and have the necessary skills to succeed.
Combining a team that is having great success with the deep ball
early in the season, with a team that is perhaps at the other end of
the spectrum in regards to 'preparedness' and offensive efficiency and
creativity, creates line value that the astute bettor can exploit.
In addition to the main conditions described above, there are a few
secondary conditions that serve to tighten the record of this trend.
Firstly, any games with an Over/Under of greater than 48 are
excluded and our focus team must also be coming off a game in which
their Time of Possession was 23 minutes or greater (TOPF is an excellent barometer of the overall health of a team, both on offense and defense).
In addition, teams that are coming off back-to-back SU wins of
>= 14 points are also excluded as they are more likely to be either
overvalued, or at risk for a let-down in the current game.
Lastly, teams that met their current opponent either earlier in the season, or anytime within the previous 2 seasons, and had a turn-over differential
(TOD) of <= -3 in this game, are excluded. Teams in this situation
have been only 90-111 ATS overall since 1994 and 4-6 ATS with regards
to this trend in particular.
Here are all the details.
(Notes: ASMR stands for Average Spread Margin Rating. A positive
rating indicates a trend that is stronger than average versus the line,
negative--weaker than average. TDIS% is the percentage of teams in the
league that have been involved in this situation at one time or
another. WT% is the percentage of teams that are .500 or better and SPR
is the average spread for teams in this situation. For more details,
please consult Page 13 of my 2007 NFL Game Sheets Guide.)
