I'd maybe put Demar up there with maybe a Corey Magette, for now. I think Demar has much more of an up-side, but I think their games are very similar.
Corey has spent his entire career at the free-throw line and has made some solid coin doing it; and scored more then a few points too. He was a solid defender, and ran the wing on breaks to perfection. Now obviously I would like for Demars team to be more successful then Corey's were back in the day, but I'm pretty sure Magette was an All-Star and did it without shooting many 3's at all.
