I know I'm going to get flamed for saying this because traditionally I believe in giving a drafted player a minimum of three years to develop, but I believe they would be better of cutting White now and refocusing their attention on players with a future on this team. Thats all I'm going to say on that.
While I'd like to say give the guy more time, where does he fit in? He isn't nearly good enough to be a QB. It seems like we're giving up on the wildcat anyway. And there is so much competition for the WR spots I can't see him finding a roster spot there.
I don't know all the rules about the practice squad, but I do know 2nd year players can be put on it. Not sure if there are exceptions like how much time he's already spent on the active roster, but that may be the only way the guy has a job in South Florida this year.
