Most top 2015 recruits have been formulating their opinions for 1-2 years now. Not like the NCAA Tournament is going to make them start over again. Clearly it made a difference with Newman/Stone to get us into the picture, but we're fighting uphill there too and I'd be surprised if we made up enough ground. Really, Adams and a big (Sharma/Enoch/Stone/whoever else) is enough to keep us moving in the right direction. We have a heavy sophomore nucleus next year - Cassell, Samuel, Purvis, Facey, Brimah - and just need to fill in some pieces around them for the near future (and then be ready for Purvis and Hamilton to leave early).
Also, Ollie just really cemented his reputation as a top notch game coach - and a guy who is considered NBA material, yet happy where he's at. In February, he was still an up and comer without much of a national reputation, and the top recruits probably didn't have us in their top tier of options. The dividends from our run are more likely to come in 2016, since those guys are earlier in the process. For 2015, the title could make a difference to someone who was already seriously considering us (I mean you, Jalen) as the final verification, or perhaps to someone who blows up this summer (a la Jeremy Lamb). Unlikely that someone just drops everything they've done in the recruiting process until now and hops on board because they watched us win on TV.
