Elton Brand pick up?

Yeah you should pick up brand, because your team is actually pretty good, but your missing a solid big man, Nowitzki is a big man, but plays like a SF, and O'Neal is a great big man, but as of right now he's going through an injury so he's not playing 100%. What I would do if i was you, is pick up brand, even if you have to drop someone, like Theo Ratliff, and then make a trade, you don't need Melo, Jefferson, and Durant all on the same team, trade one of them and try to get a solid big man like Tyson Chandler, Marcus Camby, Dwight Howard, Al Jefferson, or Chris Kaman.
