I've got no inside info, but from what I've gathered...
They want a big man, a wing and a PG or combo guard.
For big men, it looks like Elliason and Kirk are their 2 targets. Elliason was in town for the weekend, Tubby has visited Kirk several times. Elliason seems more likely. Calcaterra is a possible last resort, though I don't know if they would even offer him over banking a scholorship and going harder after bigs in 2011.
For wings, there was a rumor that we may be one of the last schools Trey Zeigler is considering. He's a top 50 type guy and would be a huge get, though I'll wait til he comes for a visit before I get too excited. They're also looking at Moses Morgan and Austin Hollins as possibilities, both are solid 3-star type guys.
For a guard, they keep saying that they're looking at McCallum, but I haven't seen anything that would indicate that it's likely. Option #1 seems to be Trevor Releford. They'd love it if Jacob Thomas got eligible, but that's been sounding unlikely lately. I have no idea who the fall backs are here.
I'd love to hear what JG or anyone else more in the know has to say, but I think that's a pretty good run-down of the relatively available information.
