This is the worse idea ever, you lose a great backup guard and great defender. Chicago doesnt need lebron.
Here is what chicago SHOULD do.
trade Deng he has done nothing for them since he got that huge contract.
Sign Joe Johnson, Bosh, and Korver.
Then you would have a starting lineup of
Rose, Johnson, korver, bosh and Noah
with Gibson Johnson, and hinrich coming off of the bench.
You have got to be kidding me? You would rather have Joe Johnson and Kyle Korver over one of the top 2 players in the league? Look I like Kirk too but he's overpaid for what he gives you. You can find adequate backup guards for 1/2 the price Kirk comes at right now. This would be arguably the best starting lineup in the East:
PG: Rose
SG: LeBron
SF: Deng
PF: Bosh
C: Noah
Anyone who thinks there is a better combination you can sign other than LBJ and Bosh is crazy. They are perfect compliments to each other and the Bulls roster is setup perfectly that they'd become instant contenders. The only drawback is Rose is a player that excels with the ball in his hands but when you have a guy as talented as LeBron next to you I see this as a plus because when you have 2 guys that can drive the lane, a legit post player in Bosh, and a scrapper like Noah someone is going to get some good looks if the defense tries to contain LeBron and force someone else on the team to beat them.
Joe Johnson would be a nice consolation prize if the don't land LeBron but anyone who would rather have JJ over LBJ is nuts.
