I'm not sure, maybe someone on this site may have more info. You would think that someone would have looked at him being that he was a local player but I could be wrong.
Read that Providence was the only BE school that recruited him.
Dunn was being recruited mostly by mid-majors early in his junior year. One of them was Cooley @ Fairfield. His stock took off that season and went through the roof during the summer AAU season. By the time Cooley took the PC job, it was pretty obvious Dunn had a great relationship with Cooley.
Both Dunn and UCONN's Andre Drummond had decided to prep at Wilbraham & Monson for the 2011/12 season. Both backed out before the school year started. Andre to UCONN and Dunn back to new London H.S.
UCONN had looked at him but backed off mid summer to concentrate on bigs, since they knew they would have Napier and Boatright coming back. Reportedly Ga-Tech, Pitt and L-Ville got interested late..
