IMO it’s between Haines, Hetherman and Wood. Coming into a new team, with personnel you have to approve and integrate simultaneously while having dramatic impact on the season result is insane.
There was only one 4,000yd+ passer this season, last year there were 6.
This year there were 0 WR's with 1300+yds, last year there were 4.
This year there was only 2 RB's who rushed for over 1500yds, last year there were 8.
Offense in general was mostly pedestrian throughout the season around the country. Aside from North Texas, nobody was really doing anything all that special. Most OC's just dinked & dunked their way through games.
