Exactly.
I think we should start Royce at the 4... let the matchup determine who Bojan guards and who Royce guards. What team in the West creates a problem for us with Royce at the 4? Denver might... Millsap might eat us up on the offensive glass. San Antonio goes big to start usually, but they will also play a lot with Morris, Gay, etc. at the 4. Lakers likely start big but their best lineups will be with LeBron at the 4 and AD at the 5.
I like Royce at the 4 because he has a little lower usage rate, is a better defender than green, and is a better rebounder. I also want him to get more minutes, so starting allows that. I think Green can come off the bench and do his Jae Crowder impression. I think the closing lineup ends up being DM, Conley, Ingles, Bojan, Rudy. We can certainly upgrade the position, but I don't see that we need to.
Some of us have yearned for a guy like Robert Covington... Can't Royce be a reasonable facsimile of what RoCo would be? Doesn't have his steal or block rate, but I think Royce also doesn't gamble as much.
