I share many of your thoughts on the future of the program. We will have to see what happens with incoming and outgoing transfers, and with Wahl, to know what needs they will have to fill.
I agree with much of your analysis of the incoming class. Gus is probably the most equipped to come in and contribute. I'm into comps so I'll share my Gus comp- he reminds me very much of a kid who played at LSU about 20 years ago by the name of Glen "Big Baby" Davis. Similar physique, wing span, soft hands, great footwork, smooth shooter and soft touch. If anything, Gus has more tools in the tool-kit at a similar age. I don't recall Glen Davis being a good perimeter shooter or post threat- he was deadly face-up from mid-range though.
I think Winter could contribute if pressed into duty, but he would most certainly benefit from a year of S&C.
Blackwell is physically ready and could contribute, I just don't see the minutes for him next year with Klesmit and Davis playing a similar role. He needs to continue to develop his shot and would likely benefit from a RS year.
