Grant had 4 double doubles and multiple 30 point games as a freshman, and averaged 2 blocks per game on top of it. He was an elite talent and doesn't exist in the same basketball universe as Tamba or even the other two, he wasn't a 3 year project, which was what your initial post said about him. Grant's 40 minute number was a freshman was 19.8/9.3/3blks. I'm not discrediting Barnes, I am simply saying Grant was an extremely talented player from day one.
Kyle was a good defensive big man and Fulkerson was a streaky player with a spurts of good play and spurts of being a ghost, even through his 6th season. Uros is the same way but with worse hands and a lower ceiling than either of those two and he's also less athletic.
This year our post play propelled us to being one of the worst 2pt percentage teams in the country. It was a glaring weak spot on the team, and that was with elite recruits in BHH and Aidoo being brought along. If we are looking a few years down the road and having to ride with Tamba, we are probably in trouble or the staff worked a miracle with him, as we all know being 6'11 and playing in the Knoxville area should mean more than 7/5 on the stat sheet. It will be an exceptional development of him if he becomes a productive SEC big man.
Michigan's big man nearly single handedly beat us last week. We need to keep recruiting there at a very high level at the position. I think Aidoo is especially likely to develop into that kind of player.
