Oy vey. Nobody said the Bulls would fall off with Wade...
You're talking about Wade going off for 46 on an aging Celtics team. That Heat team he played for in the 2006 Finals had at least a semi-effective Shaq and a deeper team than the current Bulls squad. And that Mavs team basically imploded after game 2, ESPECIALLY Dirk. I also worry about Wade and all of these nagging injuries he's had throughout his career.
LeBron is a different story, because he commands more double teams (even though his 270lb ass has no post game to speak of). He's strong enough to drive the lane and finish shots, without getting knocked to the floor every single time. Not sure how much his passing ability would come into play, seeing as how the Bulls don't have anyone that consistently knock down jumpers, unless Vinny (or whoever the next coach is) wises up and implements a run-n-gun style.
With THAT being said, a frontcourt player would be the Bulls best option. It's no secret that the Bulls are a team that shoots way too many jump shots, and need some interior scoring, considering Noah (yes, Noah) is their best scoring threat inside.
And as far as Rose and Wade playing well off the ball...sure.
