I would add a difference in our attitudes toward recruiting. Ours vs. theirs.
Call it 'working harder' or 'taking things for granted', or whatever, but MSU (Mullen, Hevesy being the prime examples) hasn't traditionally taken recruiting as seriously as some schools because of the head coach's mindset. The easiest example on the other side is Freeze, but there are others too. It's way more complex and intricate than this, because you're dealing with individual personalities, but in general:
Mullen wants to get "good guys" - guys that stay out of trouble, guys that don't mind working hard, guys that may have been a little under-talented coming out of high school but were willing to get better by outworking the other guy... all the cliches we are proud of AFTER the fact, when - or IF - he actually pans out and becomes successful (see: Dak, Beckwith, Gabe Jackson, AJ, etc etc etc.), but that we all complain about during recruiting. He doesn't want to deal with prima donnas. And I would estimate Hevesy's not wanting to deal with pre-madonnas is 10x Mullen's. They feel like they can always train up a 3-star that will work hard, so they "don't worry about stars". So, they have way less motivation to go do crazy or embarrassing things like camp out at a school for 5 days straight to sign a wide receiver.
This is not true with the Freezes of the world. He will go all out to get a highly talented, can't miss kid, no matter what his background or work ethic is. He follows the "jimmys and joe's, not x's and o's" mentality. He knows having the more talented kids on the field wins most games (and makes him look like a good coach) most of the time, so he's willing to (almost has to) take chances to make sure he gets the big name guys.
Mullen needs to move a little more to the middle in recruiting, or do like Saban and hire some high-end recruiters to do that part for him. Then introduce them to Hevesy, Sallach and the "developers" after they sign... I'm hoping that's what's going on with T-Buck and other new guys.
