Hopefully he'll be lucky and will have a good team around him and as less injuries as possible.
If that happens, he can become a 25-30ppg, 10-12rpg, 3-5, 1.5 bpg, fg50-55%, ft 80-85%
I didn't give exact number because it depand on how nuch he'll develope as a player.
If he is today's CB4 plus experience, he'll get the minimums that I've written.
If he improves the parts of the his game still need improvement, he'll get the maximums.
And as Speedy said, 50+ wins. (Why not 60+?
)
