General Rule: It's not good form to forward count recruit.
But.... It's case by case... this isn't a black/white thing...
The Harris Case:
Here you have the #8 rated recruit in the class (which by most accounts would be higher without the concerns) that has grade issues. I don't personally know how serious those grade issues are, but we'll assume that there is a enough risk here that it needs to be mitigated so you don't burn a scholly.
He will undoubtedly be better than the worst athlete in next year's class, and there's no risk in this blue shirt. If he doesn't make the grades to clear, there is no scholly forward counted. So... this situation is as light of a gray area as you can get without it just being flat white.
Ruling?
On the Crayola grayscale of of NCAA Recruiting sins, this is White Shimmer.
The Soloman Case:
Soloman is an elite 5-star interior pocket disrupter that can and will immediately upgrade your interior pass rush and run defense. You only get him for two years, but he's already in prime size/shape to contribute immediately, and he'll have a year to get used to the system and test your budding interior offensive lineman in practice. I don't have an issue with forward counting elite players like Soloman. For one, it would seem like a waste to count him this year, since he can't play, and he's the type of transfer that can reap immediate dividends.
Ruling?
On the Crayola grayscale of of NCAA Recruiting sins, this is Timberwolf, since we only get him for two years.
The Chryst Case:
Chryst, the former 5-star that never quite panned out at Stanford. He played behind a
much better offensive line, never had elite stats, had a noticeably bad deep ball, but was a high-quality backup. If they thought he'd come in an challenge for #1 duties... OK... but he didn't. So we essentially blew a scholarship for this year on a quarterback we don't have anymore that wasn't an upgrade over what we already had.
On the Crayola grayscale of of NCAA Recruiting sins, this is Slate... if they didn't expect him to win the starting job handily (in a season that was lost from the get-go), we had no business burning a scholly on him.
The London Case:
On to London, former middle-of-the-pack 3-star out of Michigan State. Not particularly fast... not particularly shifty... not particularly powerful... not particularly particular... nothing stood out about this kid. I suppose Pruitt wanted some size at RB and in desperation threw him an opportunity, but a little over 200 yds / 3TDs isn't the type of production anybody would look for from a player burning next year's scholarship on a 1 year ride. Average running backs are a dime a dozen, and while I suppose it's good we don't have to watch him for 3 more years, lol, it was a terrible scholly burn.
