It may well be that the hope all around (including Coach P's staff) was that Bradford's first semester grades would get him above the target threshold. It sounds like they were better, but as of year 3 1/2 of his high school career they are not good enough. Of course, the coach and player expect that he will get it done in his last semester, but Diaco decided not to wait. If that is the way it played out, I'd expect the coach to be disappointed, but to suck it up and recognize that it was ultimately in the hands of the player and if he was coaching at UConn he'd probably do the same thing.
Then again he might be a vindictive guy and think "they should have waited for my guy regardless." If so, there are a lot of other high schools churning out talent in UConn's recruiting area.
