Someone pointed out the other day the HC at Minnesota, Fleck. Not sure just yet he is "highly" successful, but he has made Minnesota a much more respected program. I still think when you are talking about long term, sustained excellence, you would have difficulty finding anyone with the "rah,rah" personality historically, but maybe I am wrong. I know it is true in the business world where I have worked.
What I see more times than not are guys like Butch Jones, who flamed out with his rah, rah stuff, but maybe CGC will be much different than that.
At the other end of the spectrum, you have Will Muschamp, aka "Coach Boom MFer"
His schtick of screaming at players looked great as long as Mack Brown was Recruiting lights out at Texas and was giving him a Defensive Depth Chart that had 3 future NFL DBs in the 2ndary, 2 Future NFL LBs, and 3 out the 4 DLs were future NFL guys
Musch-dawgie was able to parlay that into a Coach-in-waiting at Texas and then flipped that into the HC Job at an Elite Program like Florida
Guess what happened when he had to Recruit his own Players and Coach an entire Program from Soup to Nuts, he wasn't able to scream them into being a winning Team
My point, is that those that expect CGC to scream a guy into raising his Talent just don't understand FB or any other "Combat Sport", you prepare like hell to win, and the once the Game starts and the hitting Starts, no one not even JC himself is gonna scream at you & miraculously make you better than you are
For all of the "intensity" that Guys like Muschamp & Pruitt at Tenn throw out there, what does it really do to change their Players in game performance........NOT A DAMN THING
No amount of screaming & "intensity" is going to make our slow footed OLs find a way to block Clemson's 5* DLs even if they are T-Fr, elite talent is elite talent
That BC Team we lost to, has at least 2 OLs that are projected to be Drafted in the next 2 NFL Drafts, not Fr that might get drafted 4 yrs from now, that's why our DL got pushed around, not because the CGC didn't yell loud enough
I personally think that screamers are more of a gimmick than the guys like CGC, Dabo, Lincoln Riley, Fleck, etc, in fact Saban is starting to trend towards being a positivity guy
CGC will be fine when he gets better players on both LoS's, don't forget what Urban Meyer says, "80% of your Success as a HC is based on Recruiting"
