Since you asked . . .
Running the numbers:
PHI Offense 28.3 avg ppg + PHI Offense 6.7 adjusted ppg = 35 adjusted ppg on offense
NE Defense 18.3 avg ppg allowed + NE Defense -3.2 adjusted ppg = 15.1 adjusted ppg allowed
PHI projected score = 25
NE Offense 28.7 avg ppg + NE Offense +7.1 adjusted ppg = 35.8 adjusted ppg on offense
PHI Defense 17.3 avg ppg allowed + PHI Defense -3.9 adjusted ppg = 13.4 adjusted ppg on defense
NE projected score = 24.6
About as close as you can get and pretty much a coin toss.The only thing that is not accounted for is the Wentz / Foles factor as the majority of the Eagles offensive numbers were with Wentz at QB.
A couple other tidbits off the top in the TB12 era. NE is now 15-0 in playoff games when they DID NOT face their opponent during the regular season (they did not play PHI this year).
NE is 22-1 (.957) in the post season when they score at least 23 points. They are 5-8 (.385) in games when they score 22 or fewer points.
NE is 21-3 (.875) in the post season when they allow 23 or fewer points. They are 6-6 (.500) in games when they allow 24 or more points.
Can the Eagles hold the Patriots to 22 or fewer point? Can PHI score 24 points or more? Because that is the line in the sand where things REALLY tilt toward a NE victory.
A couple of people asked me to run the numbers again and see what the difference was between games with Ertz and games with Foles. A couple of things happened . . .
- With Wentz starting, PHI averaged 31.1 ppg. With Foles that dropped to 21.2 ppg. But that is in a much smaller sample size and includes a game against DAL which pretty much the Eagles had little incentive to win.
- With Foles at the helm, the Eagles defense performed better (not that a QB has anything to do with his team's defense). PHI averaged 19.2 ppg allowed with Wentz and 12.4 ppg with Foles.
- Based on net points allowed, Philadelphia saw a +11.9 point differential with Wentz and a +8.8 point differential with Foles.
I am hesitant to do this, but recomputing with just the Foles games (which doesn't make a lot of sense with only a 5 game sample size) . . .
PHI Offense 21.2 avg ppg + PHI Offense 2.0 adjusted ppg = 23.2 adjusted ppg on offense
NE Defense 18.3 avg ppg allowed + NE Defense -3.2 adjusted ppg = 15.1 adjusted ppg allowed
PHI projected score = 19.2
NE Offense 28.7 avg ppg + NE Offense +7.1 adjusted ppg = 35.8 adjusted ppg on offense
PHI Defense 12.4 avg ppg allowed + PHI Defense -8.2 adjusted ppg = 4.2 adjusted ppg on defense
NE projected score = 20
The Eagles defense only allowed a little over 8 ppg in 4 of the 5 Foles starts, which really distorts the impact of their defense in this formula. Put another way, the 5 Foles games extended over 16 games, the defense would have only allowed 198 points over a full season based on how well they performed in those games. To put things into proper context and perspective, only 3 teams in the salary cap era (since 1994) allowed fewer than 200 points in a season (2002 TB, 2000 BAL, 2000 TEN). Only 2 other teams gave up less than 200 points since 1979 (CHI in 1985 and 1986).
Which brings us to the $64,000 question: how to assess the Eagles defense . . . are they really one of the rare, uber elite defenses from the past 40 years (like they have played the past month)? Are they the team that was on pace to allow 19.2 ppg (making them a Top 6 or 8 defense from this year . . . not a Top 6 or 8 defense over the past 40 years)? Something in the middle?
Add that to the burning questions involving the Eagles. The first one is which Nick Foles will show up (the one with passer ratings of 69, 59, and 9 against the Rams, Raiders, and Cowboys . . . or the one with passer ratings of 115, 100, and 141 against the Giants, Falcons, and Vikings).
Add the Eagles defense to that. Will the defense perform like the one with Wentz (over 19 ppg over 13 games with Wentz) . . . or the one over the past 4 games with Foles (8.25 ppg)?
