My take is this, everything on both sides of the ball are a wash except one area.
Bosh is a great talent offensively and can rebound but Varejao is one of the league's premier defenders against players like Bosh. So that mitigates Bosh's possible large contribution. Irving is a great shooting and good passing PG but he is offset by Holiday's defense and good play-making abilities. If Green is still going to be Jeff Green and kinda be there but not be spectacular, then the same can be said of Young, who's stats for 3 years have been almost exact replicas and who disappeared in last year's playoffs.
The benches are both strong and deep but its the playoffs and my guess is both teams will be down to 8-man rotations with Brand/Gordon/Kleiza getting the most run off the Mavs bench and Splitter/Jack/Parsons getting most of the Bulls PT.
So that leaves the superstars and whether they can convincingly beat their matchups. On paper it says Wade is the easy winner over Sefalosha whereas LeBron is taking on one of the better SFs in the game. here's the thing, over the past two playoffs, LeBron has absolutely owned Pierce. LeBron has taken his game to MJ level of greatness and I don't think a year from now LeBron is not going to own Pierce just as much. The Captain will have his big game but LeBron will have a monster series as the thought of ring #2 gets closer and closer.
Wade is one of the greatest superstars in the game today, but with a long, athletic defender on him, I don't think he can raise his game to the heights that Lebron can any more. The Miami Heat are LeBron's team and Wade is now playing the older, more beat up version of Pippen to MJ.
LeBron's ability to elevate his game and put his team on his shoulders wins this series because the collective trio of Bosh, Wade and Pierce will run into a defensive buzzsaw in AV, Lebron and Thabo. I see frustrating periods of an inability to score for that Bulls team and for that reason:
Mavericks in 7.
