I think the Saban-Carl comparison is a good one.
Saban was good at MSU. Then he moved to a hotbed of recruiting where he can load up on top end talent. He has the recruiting skills (like Carl) to get the best of the best to sign on even when there are players just as good to compete for a spot against. And he is willing to kick the loser of the battle to the curb and “encourage them to leave”. And if they have a very good starter but find someone better, he is willing to kick the starter to the curb. It is cut throat winning. I couldn’t do it - I am too loyal and honest to do that to someone, but it is a skill that makes a dynasty as long as you can keep your players/wrestlers happy and keep them coming. One might even say Brands doesn’t have the cut throat killer instinct to do it - he is too loyal to his people - great trait for a mentor/role model, but not necessarily for a cut throat winner. I doubt very much that TnT even considered recruiting over/transfer portalling in a guy over Kennedy. Carl didn’t hesitate to do it to Facundo or to Beard.
And some coaches can stack the talent but still can’t win/underperform (see Texas and ND football, maybe throw tOSU, Michigan, and OSU wrestling in there to some degree [though not great examples]).
Saban and Carl have it all right now - The top end talent stacked deep, financial backing, and enough skill to make it all work.
Saban is a good coach but couldn’t make it work with the Miami Dolphins where he didn’t have superior talent at almost every position. He couldn’t develop a dominant team at MSU. Could Carl? Maybe, maybe not.
