Individually I love Wallace's game, the D and the hustle/slashing role he plays is a lot of fun to watch. But as far as a piece of the starting unit I don't see him fitting so well with this team, with his lack of outside shooting and what I hope will be more of an inside-out game once Greg is healthy and adjusted.
I would have given quite a bit to get Danny Granger from the Pacers, his offensive repertoire fits perfectly with our starting unit and he's got some developing skill on the defensive end as well, plus he fits in perfectly age wise with our core. But with Bird giving him the big extension it's pretty clear they're committed to building with him as a major piece of their foundation, so it's all but impossible to see him coming our way.
Another great young wing I'd be ecstatic to make a move for would be Thaddeus Young, he's got such an efficient game, and with adding the 3-ball like he seems to have done this offseason he's got the potential to be an absolute star SF (I already think he's in the same conversation with Durant as far as last years rookie class goes, and if he keeps up what he's started this year I think he's got the potential to be hands down the better of the two). But I can't think of any really likely scenarios where Philly would be willing to part with what looks to be an up and coming allstar.
