We'd need to hit on all five for this to be true. I take your general point, but let's not overstate the class yet. Frankly, it almost certainly needs Achiuwa on it for it to be even close.
We had a class of Drummond-Daniels-Boat in Calhoun's last year. 247 has Drummond ranked oddly low (I remember him being consensus Top 5), but if my memory is right, they had two players (Daniels and Drummond) who are ranked higher than anyone we're after except Achiuwa (who would be equivalent to Boat), in addition to Boatright, who is ranked higher than either of our guards.
I think this class has potentially to be very good. But UConn has had very good recruiting classes before.
