With all the talk about Ray Allen or Michael Redd, what about Joe? Of the 3, he's probably the least likely to earn a max contract, though he may himself get one. He shot 47% from 3 this year, averaged 17.1 points, 5.1 rebounds, 3.5 assists as their small forward, but he can clearly play shooting guard. He's 6-7, 230lbs, and showed how good he is during these playoffs.
This isn't so much about how we'd get him, or why it would happen, but mainly about how he could be a great fit here, I think.
I'll throw this out, but perhaps you could get him for Jack and expiring contracts. If he wants to stay in PHO, it's a moot point, but if he's interested in heading somewhere else, we could try to get him via a sign-and-trade deal.
