Honestly, neither player impressed me that much during the past season. I think Konate is slightly ahead, due to playing a full season, but they both have a long way to go to be productive players while playing major minutes. And that is my concern - if you have a really strong program with a lot of quality players, I can see taking a flyer on a raw recruit with potential. But, given the Gopher's situation, this was a heck of a gamble by Pitino. The Gophs are going into next season (barring any late recruiting moves) with one of the youngest and least productive C/PF combinations I can remember in nearly 50 yrs of watching Gopher BB. If Gaston and Konate do not take some major steps forward in the off-season, next year has the potential to be really ugly.
I hope I'm wrong, but that's my honest opinion.
