i don't think Fields is top 5 going forward either, maybe not even top 10 (Evan Turner or the Johnson guy from Wolves may push him out).
as for George, he played the 2nd best D on Derrick Rose that I saw in these playoffs, after LeBron.
And he's a rookie. He had a rough rookie year because Indiana was a mess, but he's good. At the very least, he'll be a very very good defender.
Amazing defensive quickness for a big wing.
(PS I think he'd be a perfect fit next to DeRozan at 3)
Patterson I think is the best player of that group right now btw.
Very mature player. Very mature defender especially. He's similar to Taj Gibson, even more physically gifted, and he can also make a jumper.
If he didn't play behind Scola, he'd get way more attention.
But I just don't think he'll improve much. He's older and he's stuck on a team with at least 4 PFs.
So looking forward, I'd probably take Davis.
