Not quite, he is closer to 7 RPG than he is to 8 RPG. Oden might be playing less minutes, but I don’t know if rebounding rate is good enough to determine who the better rebounder is. Does Oden have the stamina to play 34 MPG and rebound at the same rate? Can he do it in a run and gun offense like David Lee? Does he get as many back taps to teammates as Lee? Those are all questions to consider. I don’t think you can say Oden is without question the superior rebounder, it’s definitely up for debate.
It's up to debate, anything is. I just don't think the numbers are deceptive. Oden is an enormous rebounding presence. Lee is a good rebounder, but he doesn't seem at all dominant to me, when I watch him.
His playing style does not reflect that of a point guard. He could technically be labeled as a point guard, but that doesn’t matter unless he decides to play like one plays like one. For example, Jamal Crawford was also drafted as a point guard but plays nothing like a one.
He was playing shooting guard at Arizona, so that affected his playing style. I assume that's what you're referring to when you talk about his playing style, since he hasn't played enough NBA minutes to have established a "playing style" at this level.
At Arizona, he was pencilled in as the point guard, but had to be shifted to shooting guard when their expected shooting guard was injured. Playing shooting guard, of course he wouldn't play like a point guard. That doesn't say much for what he "really" is.
I think he isn't a true point guard at the NBA level, but I think he has the potential to be a scoring point guard, like a prime Stephon Marbury or Steve Francis.
You just proved why he’s a tweener

He doesn’t have ideal SG height, but he doesn’t have the instincts or court vision to play point guard fulltime. A combo guard is a player that can comfortably play both positions on both sides of the ball.
A combo guard isn't a player who can "comfortably play both positions." Almost all combo guards are scoring guards who don't quite have the ability to be a true point guard. Anyone who can be a true point guard plays point guard, because true point guards are far rarer and more valuable than shooting guards.
IMO, "combo guard" refers to skillset and "'tweener" refers to size. Bayless is a combo guard because he has skills of both point guards (ball-handling, passing) and shooting guards (shooting, slashing, finishing). He's not a 'tweener, because he's not "in between" point guard and shooting guard heights...he's ideal point guard size. He'd be a bigger point guard, but not oversized.
You don’t have to be a catch and shoot/drive player to mesh with a distributor. Roy will still have plenty of opportunities to isolate and create for himself and his teammates. Furthermore, a distributor can have scoring ability as well.
I'm not saying that a distributor can't have scoring ability or that only catch-and-shoot players can mesh with distributors. My point is that two people can't be primary on-the-ball players. Roy's strength is that he's capable of being a primary on-the-ball player. Those types of players (who are also really good) are fairly uncommon. Another primary on-the-ball player would mean that either he or Roy would be wasting that ability to be able to run the offense. It's not like I'd turn down a young Steve Nash, or a current Devin Harris or Derrick Rose. But since Portland doesn't have one, paying what it would cost to get such a player would be a waste since Portland doesn't need such a player with Roy.
