You're getting a little dramatic if it's "win at all costs." Kids aren't doing steroids, they're not raping women and being kept on the team. They're slow playing kids who aren't performing as well as they were. It's not much different than your company laying you off if you spend too much time on northwestern.rivals.com.
It's a fine line to balance, because you see coaches like Pete Carroll, Nick Saban, and Jim Tressel reap the glory of bowl games and national championships while pushing the line. The Patriots are also known to push every advantage they can. Rarely, if anyone gets caught, the penalties are a slap on the wrist. Tressel was given a standing ovation when he went back to the Horseshoe. Carroll is still a hero at USC.
Michigan is in the tough situation where it thinks that it's still one of the top programs in the country, and does it with honor, but it really is falling behind the SEC and the other programs that have no problem pushing boundaries. The last decade of NCAA champions have all had that mentality (OSU, FSU, 'Bama, Auburn, FL). The last winner that doesn't have as much of a stink around it is probably UTx in '05.
Fitz does seem to do things the right way even though someone else posted some instances where he did similar things with kids. Northwestern and Fitz are certainly classy institutions, but have also been decidedly mediocre in the Fitz era (60-53 before this season). I suppose it depends on what your goals are. I don't think NU has any dreams of competing for national titles or playoffs on a consistent basis. You can absolutely do that with honor. But to be as good as Michigan wants to be, Harbaugh is going to have to cut a few corners. If you can name a school that competes at that level without doing anything suspicious in your mind, I'm all ears.
Naming them isn't the problem, my friend . . . it's DEFENDING them.
