I don't follow the NBA very much these days so can't engage in a discussion on who's the best player in the game right now, but I just find it hilarious when people bag on a player because his TEAM hasn't won an NBA title.
Remember that Michael Jordan didn't win any titles either until he had a better supporting cast - it doesn't mean he wasn't a great player until the NBA Titles started to pile up, does it?
Again, I can't really comment much on who's the best player in the game right now, but judging a player based on their number of championships is flawed logic.
It's like saying that Ernie Banks wasn't arguably the best shortstop in the game during his era just because the Cubs always stunk.
