I know there are some kids that may look elsewhere that want to start right away, but the ones that are willing to be a piece of the puzzle (like Coates and Wilson coming off the bench this year) will be good fits.
SC also has the Cliney girl that was red-shirted this year. So there's one, plus the Canadian kid, that's two. It will also be time for some of those other freshman to assert themselves. Jatarie White was a McDonald's All-American who had to play behind Ibiam and Coates, so it will be up to her to work hard this offseason to be that second-post player (similar to what Coates has been). If she busts her tail, I think we're good there.
Welch is definitely the hardest to replace from a leadership standpoint. Will be interesting to see who takes that role next year. Doesn't have to be your top scorer to be the leader.
Staley rarely has a big roster, so I don't see her signing more than 1 other kid this year. Most of the recruiting being done now is probably for the following year, but that's just a guess.
