LaFleur?
My opinion of the moment is that LaFleur's success/failure is going to rely on whether he gets along with Rodgers -- not really X's and O's, talent evaluation/development, great motivational speeches or anything "coach-like", but on how he handles that one guy on the team, the franchise super star. So, for talk about experience, I'm not sure there's anything that can prepare any coach to handle Rodgers, and because of which, I don't see the supposed lack of experience as any big deal.
I mean, it's almost like an NBA coaching situation with the big ego superstar. Veteran Rudy T won a couple championships but couldn't last a year coaching Kobe. Tyronn Lue, as an interim head coach in his first try at head coaching, got LeBron to win a Championship for Cleveland. Lue was credited with being able to get in LeBron's face and actually coach the big ego superstar.
Before the Rams hired McV, they stuck him in a room with Goff and got Goff's feedback. I like to think the Packers did the same type of thing before hiring LaFleur. So assuming LaFleur passed the discount double check and got Rodgers' blessing, things should go smoothly for at least the first few weeks. If they hired LaFleur without Rodgers' feedback, then yeah, this has fail written all over it.
Also, talk is that they're going to keep Pettine to handle the Defense, providing some continuity and a veteran coach in the locker room.
Best wishes to LaFleur except when the Pack play the Rams and when we need the Pack to lose.
