This is a what if that does not and will never actually be on the cards for anybody at any time. It's simply an interesting idea. What is this crazy idea? you ask. What if you traded Pau Gasol for Dwight Howard?
Howard is the best defensive player in the league. He's one of the few real centers left and he's been proven as a great chemistry guy and team mate, there are questions of his killer instinct but there are similar questions about Gasol. Howard is not a good post-up player. He has one move and it's not very good. He tends to bowl other players over and try a very odd hook shot which will kill a team one day and kill his own team the next, so much so they'll just stop going to him. I'd say he doesn't really demand a double team unless there's no center on the opposing team.
So who says no first? I think the Magic say no first. This is because they would have no interest in pairing up two of the "softest" power forwards in the league up. A front court of Rashard Lewis and Gasol would not intimidate anybody except high schoolers. They would however score on basically anybody they'd play against, it's intriguing but not really.
The Lakers think about it. They then come to the conclusion that they already have Andrew Bynum (while forgetting that he's always injured when it comes to the playoffs) and that they couldn't do a whole lot with Howard at the offensive end. They are intrigued by a possible defensive lineup of the Artist Formerly Known as Derek Fisher, Kobe Bryant, Ron Artest, Dwight Howard and Andrew Bynum. Yikes. Who wants to go up against that? Nobody is who. In this scenario the Lakers rely heavily on candy man Lamar Odom who shows up every other game because he's basically diabetic at this point. This is not cool.
So to sum up: neither team really wants this as the players are vastly different and because of this they serve an critical purpose on their teams respective defensive or offensive schemes, and neither player can compensate for their deficiencies or the others skill set. Basically if they played on the same team you'd have the best front court in the league. They would be perfect for each other, a ying and a motherfucking yang bitches!
(According to the ESPN trade machine the Lakers would win 7 more games and the Magic would lose 7 more games if this trade were to go through).
