People there is no certainty in him coming back. Sure he intends to and he wants to but that does not make it certain, especially if he is looking to announce late summer. His actions reflect 'I am coming back BUT I will wait until August to 'officially' announce'.
Calhoun simply has not stated what the 'BUT' is which is leading to speculation, uncertainty and assumptions. It could be health, Ollie, control, in-fighting, depression, etc... Who knows?
Nonetheless, this drama certainly does not help stabilize our program in its most significant situation that I can remember in UConn Men's bball history.
