It's gonna take more than that. As of right now, he's not quick enough to be the player you are describing. You can't just be a rim defender. You have to defend the PnR and every team is gonna make him do that until he proves he can. This is why Tacko Fall is in China. This is why Boban plays < 200 minutes a year. If he's a big liability there, it's gonna be hard to get any meaningful minutes. His teammates won't like that he's a space eater on offense. He may get some buckets but he presents a problem if he's clogging up the driving lanes.
