If he is, he will see why he needs to incorporate his running game into the offense better. As I watch this game, the Saints offense is built almost like the Bills is. Sproles is essentially Spiller and Pierre Thomas is Fred Jackson. They are keying the win tonight. Yes, Brees is playing a GREAT game, but when the defense needs to be kept honest, they are running the ball well.
I really hope Chan watches this and sees the light about how have 2 great running backs can make your offense that much more potent. Hopefully Fitz notices how Brees doesn't throw into double coverage and is cool with just throwing a ball away.
As far as I'm concerned, the Bills need about 4-5 quality players (2 Pass Rushers, #1 WR, and upgrade for Drayton Florence and probably a QB, but hopefully an improved team makes Fitz at least passable for a playoff run) to make it to the playoffs. However, even more important, Chan needs to recognize how to use all his players and embrace the run a little more.
The Bills are inching closer to relevance, but an improved D will mean nothing if Chan doesn't stop going 5 wide every play. Hopefully the Saints are showing why a running game is so important even in a pass happy offense.
