Probably not a lot. His strengths appear to be baserunning, outfield defense (in particular his range, not his throwing arm), and his contact/OBP skills. So for the 50 games Braun misses, he could play quite a bit, probably be a 2 hitter in front of Ramirez/Weeks/Hart and put respectable R and SB numbers up. If you play in an OBP league, he might help there too. But I would expect next to nothing in the HR and RBI categories. I don't know, I don't think there's much to see here.
