I think this is the perfect time to do it. This is a transitional season for us. We have several guys moving to new positions. I would rather Wand learn this year than next. I am earmarking year 4 as our breakout year. Could it happen this year? Sure. Is it as likely with all of the roster reshuffling? I don't think so.
I'm curious to see Milford Brown's progress this season. Hopefully he can live up to his potential. If so he might push one of the interior linemen.
I like Pitts at LG. He will be a Pro Bowler there some day IMO. He is a great run blocker and playing on the inside should improve his pass-blocking as well.
