As long as it still has "University of Dayton #0" in the bio, he's confirmed. Seriously, it seems one of the first things "kids" do is update their twitter info.
Earlier in the month, I periodically checked Jordan Pierce's account and it never changed, so I was 99.9% confident he was keeping his commitment.
