There have been some very good points made in this thread. I would simply add that we need more stability with our roster. I'm not sure what Dabo has done at Clemson to limit the attrition from year-to-year, but we always seem to struggle with losing players that we didn't intend to lose.
I think Gus needs to do a better job getting to know these players individually and determine what he can do to make each individual player successful. You can't make everyone happy, but I think we can do a much better job. My example of this is Rodney Garner's coaching style. If certain players aren't responding to that, then Gus needs to step in and determine the support those kids need to be successful. Byron Cowart & Antwaun Jackson weren't recruiting by everyone for no reason. Get in touch with their high school coaches or their families and see what motivates them.
That doesn't mean that you put up with insubordination. But ESPN's 30 for 30 "The Best that Never Was" is a prime example. Marcus Dupree didn't respond to the criticism from his coach Barry Switzer. His family member even stated that if you cuss Marcus, he'll lay down on you. But if you praise Marcus, then he'll run through a brick wall for you.
Bottom line - we need to get to a full 85 man roster of scholarship players instead of having to hand them out to walk-ons to fill the 85 limit.
