I liked the Fox decision when I saw his assistants. He was also a natural fit with Hurney, and I'd said so at the time. Of course, even at the time, I was tentative about Henning, and wanted a QBs coach.
I would have taken Marvin Lewis - I'll be honest about that. Dungy never would've come, and he'd have problems here on offense, too. Going there, with established OC, QB, and WR, was necessary. Would I have taken Lewis over Dungy? Yeah.
I said it then, and I'll reiterate it now, I'd have brought Willingham in, provided he would be willing to bring in pro coaches for the most part. That was a point of contention with Spurrier - his offensive staff was a joke, remnants of the UF staff and without an OC (I believe) and with his kid as QBs coach. That's not a staff.
As for Spurrier over Fox, I don't know. I bought into the hype a little, but I assumed he'd have acted like a pro coach, and I think JR saw it wasn't going to be that way. I'm glad.
At the time I was unimpressed with Fox' resume, but I knew he could bring the intensity and the discipline that Lewis could. Looking at what Lewis has done so far, with nothing, the way that team's supposedly snapping to attention (save Dillon), I do believe that Marvin Lewis would have been at least as good a choice at the time.
Right now, I can't be any happier with Fox. I'm frustrated by the lack of a young QB to bring in, or a balanced offense - neither of which seem to be on the agenda.
