We're definitely turning a corner, and the transfers both fill crucial niches. Credit the staff for identifying the need, to put it bluntly, to recruit over some of the chaff that we picked up during a subpar recruiting period (2012-2014). And, not just identifying the need, but succeeding! For Gibbs, we beat out OSU and Pitt, two decent P5 programs. Miller I believe had high-major interest as well. That's noteworthy.
I don't think I'd categorize Diarra in that way -- it's not like you can point to his commitment and say "UConn's back". He's a nice start to the class of 2016, but he's also a sub-100 recruit for whom the only competition was an imploding mid-major.
I think the real test will come with guys like Gilbert, who are clearly on the radar, highly ranked, with multiple high-major offers. That's not to say Diarra won't have an impact on the court -- I firmly expect he will, and I expect his stock will go up even over the next 12 months. But I think Ollie's recruiting mettle will really be tested with these top 2016 and 2017 targets.
Still, we should feel a lot better about our place in the college basketball landscape today than we did 2 months ago.
