In the right situation he could do very well.
He was trying to carry the entire load and playing with injuries as a Wiz. Naturally he can't do that anymore, but he can play as a supporting member perhaps with a good big man. He wouldn't be a good fit with another good guard, he'd have to play with a big man that commands double teams and is a defensive presence as well.
With a slightly reduced role, good big man and less minutes he could be very effective and may even have a couple 4o pt games and a 50 pt game if all things are aligned in his favor (rest, rest, rest).
