He is a great coach period, he just didn't get along with ownership here and moved on. Im sure we all have worked for people we didn't like then moved on.
Great "college" coach you mean.
Making his own NFL front office draft decisions (by far not limited to passing on Aaron Rodgers for a part time SEC RB and signing a journeyman QB best known for banging his head against cement walls), his sideline coaching (and especially unmasked after losing Scott Linehan as the OC), considering you are what your record is, I guess he can charitably be depicted as a "mediocre" pro coach; personally, 2 games under .500 with a significant trendline pointing down at the time he branded himself as a "lying quitter", I'd more realistically characterize him as a "below-mediocre" NFL HC and defacto GM. :idk:
