Good for him on deciding this now and not waiting and putting himself and UConn in a tough spot a year from now or after he arrives on campus.
I wonder if this is at all related to the expansion of available scholarships for baseball. Before the change this week, he may have only been able to get a partial scholarship from baseball and needed the football end to get a full ride. But now with the expansion of full-ride scholarship available across college baseball, he now is able to get the full ride from baseball alone and doesn't need the football side to get a completely free scholarship offer.
Maybe not, but the timing of the decision and the rule change made me think it may be a possibility.
