Fact is, Bulls were a 7 seed in the East and nearly took down the eventual champs with Chandler and Sweets as their main big men. Now, they have Wallace (which weakens Detroit as well) and even if he has weaknesses, he is ten times the player Chandler is. Then when you factor in the possibility of getting PJ for Chandler, you have a frontcourt of Nocioni/Deng/Wallace/PJ/Sweets/Allen, whichever 3 you want to throw out there. It lowers the PT for a guy (Sweets) who is much better when played in quick spurts, gives Noc, Allen and Deng a guy in the middle who can attract some attention and open their shooting up more, and he improves the defense in a huge way. This won't singlehandedly put the Bulls as the East favorites, but it goes a much longer way than you'd normally expect due simply to the complete ineptitude of the Bulls' 4 and 5 in many games last year.
