Harden vs. Carmelo? Who would you want?

Seeing the fluid ball movement from the Rockets w/o Harden, stiffer defense, it brings the question, how good is James Harden?

He's not a top 10 player, maybe top 20 talent wise. His game is not much different than Carmelo.

He's a pure iso-player, however he's not as lethal as Carmelo on offense, and his defense is much worse than Carmelo. And we all know Carmelo will never win a ring with his style of play.

And it's starting to look like once James Harden comes back, the Rockets will never win a ring either. You can't have a player who stops the ball on offense and then play no defense on the other end. If Harden is hot, Rockets will win, and if Harden is not, the Rockets get destroyed.

LeBron learned it the hard way. The Heat have one of the most fluid offenses in the league. I'm just disgusted watching Harden go isolation and stopping the ball. What's the solution?
