I can see why we got Lee...he's the best roll to rim guy we've had in a while.
Tyler Zeller actually led the league in points per play on rolls to the rim. He and Lee form a pretty strong combination in that regard, and you can switch either of them out for Amir and not lose anything.
Those three will probably see plenty of court time and run endless pick and rolls with Smart, Turner, and Thomas.
Should be the bread and butter for the offense.
