Still new here, but I don't understand all the fascination with Josh Smith. He's going to command somewhere between 12-16 million dollars year, and I personally don't view him as an elite player. I would rather try to spend a chunk of money that large on a player who has the potential to be dominant at his position - like a Lamarcus Aldridge (Just an example at PF). Why not use that money on a few contracts for other very solid but not great role players?
People like Josh Smith because, when he's playing at his best, he's a game-changing player. He's very athletic, plays with good effort, can defend multiple positions, and can handle the ball very well for a 4. People don't like him because he's enigmatic, sometimes falls in love with long jump shots, and doesn't have KG size for the 4.
Personally, I think he's the Rondo of power forwards, good and bad (which may help explain why they're apparently pretty close on a personal level.) But I love Rondo, even if a couple of times per game I yell at him, and I imagine I'd probably have a similar opinion of Smith if he were on the Celtics.
A lineup of Rondo-Bradley-Pierce-Smith-KG would be defensively stifling. If Bradley's offense continues to grow, it could be solid offensively as well.
