Hard to know where to start here, but:
1- "offensively they were both 5" ... umm, no. CM is a stretch 4 at the college level. He's tall enough to slide over to play the 5, but at 230 or so pounds, it's an uphill battle for him in that spot. As a PF, he can block shots and finish over size at the rim. His face-up game is less developed than his post game ... but he has both (unlike TR) and both will improve. He's a classic, long PF in JB's system, which is why he's playing in that spot, just as Hak did and Coleman years ago. He has an outside shot, but so what. So does Rak, doesn't mean he's a SF. So not sure where you're going with this except to criticize JB.
2- "You want to start two guys who can't play with the ball outside 15 feet unless it's to catch and pass". This is wrong, again, as to both players. Right now, TR doesn't have an outside game. It's a WIP, and when it arrives, he'll be an excellent SF for us. The only reason he's playing inside is that CM is hurt. As far as CM, I'm not sure if you've been watching the team play, but he has an outside shot, and has taken and made at least one 3 this year (although that's not his primary role with the team). And before injury he shot regularly (and had the green light from JB to shoot) from 12-17 feet. That doesn't change the fact that he's 6'10 and is, by far, best suited to play PF for us. Sure, he can play C in a pinch against smaller teams, just as Tyler can play the 4 in a pinch. But not when we're playing better/bigger teams ... as most of us have already seen.
3- If you want to see where JB would play TR and CM, just RW your DVR back to the first 8 games, and you can see where they fit. Yes G started at the 3 when Tyler was out a couple games. Does that surprise you? G's also a SF. But neither he nor TR belongs in the trenches fighting on the glass with Kennedy Meeks, or Montrazel Harrell, etc, etc, etc...
