Factual based on what? n
Originally this was about 8 in the box. Data, while a few years old, indicated the lions face 8 in the box no more or less than average. There is nothing to suggest that has changed.
The defense you face has more to do with your formations than who is in the backfield. If you go 4 wide single back set, you're not facing 8 in the box if your running back is Barry Sanders or Zach Zenner.
Good players help the team no matter what position they are at. So does a great RB help the team? Absolutely. Just as a great TE, LT, C or any other position would.
I didn't watch the game last night. But do you think they were stacking the box against Jordan Howard? The guy came in with 55 yards the past two games combined, running at a 2.5 YPC. The guy had a good game.
I'm guessing an elite WR does as much if not more to help the QB and team than an elite RB does.
Everything helps. Stafford getting hit at one of the lowest % of dropbacks helps him. Play calls help him. After the catch plays help him. But the biggest reason he is better this year, is because he is better. He is making the correct throws, he is being very accurate, and he seems to have an improved pocket awareness. So the biggest contributor to the QB playing well, is the QB, which is always the case. Good QBs are good, because they have talent, not because of running games, not because of WRs, etc.
