I'm not saying they aren't a very good team. They are. Great coaching as well. You missed my point, though. The landscape of college football HAS changed significantly since the dawn of the NIL/transfer portal era, and we're only now just beginning to see the results of it. To ignore such things is to be behind the curve. It's why a guy like Saban left. He saw the handwriting on the wall. He couldn't do what he had done in the past, which is to recruit the very best talent AND retain them.
The very best programs/powerhouses, Alabama, LSU, Georgia, Clemson, Ohio State, etc.., could still recruit the best talent, but they couldn't retain them, retain their depth of talent, and reload as quickly and comprehensively as they were accustomed to. This has created a situation where they couldn't remain quite as dominant as they had previously been, and made it possible for other teams to poach such talent, or develop their own and close the gap.
This is why the SEC has recently lost its dominance at the tippy-top of the hierarchy, though they still remain the strongest conference from top to bottom. There's a reason why Alabama and Clemson dropped off so fast from the top of the hierarchy, and there's more potential for a team like Indiana and Mississippi to do what they've done. There's more potential for a team to suddenly emerge as a contender in this more fluid age of college roster construction.
It's happening right under our noses. What's Indiana without Mendoza and a few other valuable talents they acquired from other programs?
