The scoring number got inflated with the 104 points scored against the Jets and Jaguars at home. They averaged 52 point in those two games and 23.8 points against everyone else, which would have had them at 16th.
The scoring percentage is an interesting stat. Can't get much better than 2nd. I think red zone TD% is the best number to look at and the Patriots were 11th there which isn't bad. There were some encouraging things about the offense and they should only get better with more experience together however they really need a #1 receiver and a better slot receiver to make a significant step forward.
I also think it's fair to say we could have expected better from individual players... for instance Henry looks to be a reliable red zone target but I don't think he'll be all that productive in between the 20s... that's where Smith's production really needs to pick up but there wasn't much encouraging about his play all season. The two 3rd round TEs look like bad draft picks. Agholor was a complete disappointment while Bourne exceeded expectations. Meyers is 4th or 5th receiver. Harris and Stevenson couldn't have been expected to do more. Even Bolden was a representative replacement for White. Not much more could have been expected of the rookie QB.
Tough to evaluate the team as a whole since their season breaks down into three distinct segments:
2-4 beginning
7-0 middle
1-4 ending
They weren't as bad as the 2-4 starts looks because they easily could have won 2 more of them (Miami for sure). They caught a lot of breaks during the winning steak with opponents injuries, the wind storm, and a pretty soft schedule there otherwise. The 1-4 finish is obviously concerning, especially the big losses to Buffalo, who are an even better team now from the end of the season.
