I think what Young has done this off-season is really encouraging. In order to play the 3 in this league he needed to gain strength. If he's done that, he can at least get by defensively.
His talent is such that he could eventually score 20+ PPG in this league. Any step he takes toward reaching that potential could be huge for this team. We need a wing scorer, and he could very well be it.
I think people are ignoring how much this team has come together. There's real leadership here, and with Smart, Bradley, IT, Crowder and now Amir, we have one of the most mentally tough teams in the league. Youngs the kind of kid who, if he was in Philly, would probably never reach his potential. With this group you can tell he's getting what it takes to be an NBA professional.
