I'm not saying he couldn't eventually be the starter, but Monty wants to win games now and if Withey absorbs the playbook like most rookies do he's going to be out of position for months. You have to hide a guy like that against 2nd units.
If he's gonna play at all, he's got a much better shot at success playing 15 minutes per night with our starting unit than he does playing next to Anderson.
Defending the pick n roll with Holiday vs. defending it with Roberts.
Saving Davis a few fouls per game. I think those areas are where his value would come from come.
In the end, i doubt it matters though because i seriously doubt we'll be picking between Jason Smith and Withey as our opening night starter.
