Lol it's clear we could make cases for everyone being coach of the year if you want to do that, here's McElwain's case.
First year head coach
Projected to be second to last in the east
No O-line what so ever.
Projected to be an underdog in every game
Didn't really have decent QB play until midseason
Starting QB suspended.
No solid running game
Only two solid receivers
No kicker
No 21. in recruiting compared to Clemson's No. 8
I hear what you're saying, and I think McElwain has done a great job in his first year.. But hang with me here, he won because of Muschamp's recruits on defense this year. Muschamp did awful at Florida, but he recruited great defensive guys and their DC kept them playing well. Their offense was a steaming turd all season, which owes a lot to Muschamp's failure to recruit well on offense.
What McElwain has done is really hard to quantify because of where the SEC East was this year and given what they did/didn't do on offense combined with how great their defense was.
