I don't think there's anything wrong with comparing the two players. There wasn't anything wrong with doing so for Manu and Tony either. It's the endless pissing matches and predictable responses by people in the various camps that I could have done without.
Personally, I think White is the better player and should start. I also think there are scenarios where it might make sense to not bring back Murray after this season or to trade him. That doesn't mean that I don't hope Murray plays well or that if he does well and the team moves on from White, I'd be unable to move on. I just have my idea of who is better and am fine saying it.
