He is a really good play designer and play caller, a great developer of QB's and an underperforming recruiter. I hope he will improve in recruiting performance.
His record as a UF coach is all that matters.
Right now he's 6-0 (3-0) with wins over Miami, Kentucky (revenge), Tennessee, and a top 10 Auburn this year.
Overall, he's 15-3 (8-3) or 83.33% (72.73%).
Additionally, he seems to genuinely love UF, the players and his staff. He emphasizes hard work and determination. He prepares our players well, is well spoken, less off-putting than I feared based on hearsay, and has brought sustained fun and excitement back to Gator Nation for the first time since Meyer.
Go Coach Mullen! Keep straining to improve (especially in recruiting) and keep having fun!
