It will be very interesting to see what happens next season with a new OC and QB coach - and - more importantly in my book - likely 2 or 3 new starters in the O-Line. The O-line was a patchwork situation all year. They were OK on pass protection, but I thought the run game was very inconsistent. Better O-line play = more consistent gains in the run game = fewer 3rd-and-long situations.
I don't have time to get into this debate again, but I still maintain that execution trumps play-calling. A run up the middle for 1 or 2 years could be a bad play-call, but if the center and guards give the back a seam, and he pops it for an 8 or 9-yard gain, suddenly it becomes a good play call. More often than not, you win games by out-executing the other team - not by "tricking" them with some surprise play call.
One final note - NO MORE ONSIDE KICKS EVER!
