Same guy yes, but giving him game experience this season would probably make him better next season, but that would also leave the potential of having five freshmen next year (R-Fr Buggs, Ellenson, Fr Foster, Ellis, third 2013 recruit).
At the same time, if Tubby plays him this year, he will have very little game experience before we start trying to tackle our beast of a conference this season, and he will only be playing for about two thirds of this season, or less if he gets injured again.
I can see what you mean, that it probably won't have a great effect on next year if he redshirts or not. Game experience this year will help him next year, but you also have to wonder how much playing time is available for him right now, and if having him on the court helps the team. I haven't seen any of our guards play so horribly that I absolutely want them out so that Wally can go in. As eager as I am to watch him and Buggs play, I'm leaning toward thinking that redshirting might be the better option right now.
