If you give me a natural poing guard, shooting guard, small forward, and center, who would you rather have filling the fifth spot, a natural power forward in Barkley or a better player in LeBron James who can take advantage of his matchup offensively and hold his own defensively?
The 1992 team doubtlessly had superior shooters and passers, but LeBron James is probably the second greatest point forward to play the game next to Magic Johnson, and although Jordan is the better player, the totality of the impact LeBron makes on an individual game may be in fact be greater, and Durant, CP3, Kobe, and Kevin Love are more than serviceable as outside threats. While LeBron's post game is far from polished, he dominates the paint for stretches, must like we saw throughout the playoffs. He's the ultimate pick your poison player - he can pick you apart by passing and scoring. Chris Paul isn't quite on the Magic Johnson or John Stockton level in regards to court vision, but he's pretty damn close. With him and LeBron hopefully using the ball more than any other players on the team, I don't think the 2012 team would be any slouches in terms of ball movement, even if their attack is more perimter oriented while the 92 team's approach would be primarily to pound the ball inside.
I don't doubt the fact that the Dream Team would win the battle of the boards, but I think some, not all, of the descripancy in size can be compensated for by the freakish athletes the 2012 team posseses.
Do I think the 2012 team is better? Of course not. But I could easily see the 2012 team winning on a given day where they're hot from beyond the arch. In a seven game series the 2012 team wins maybe 1.5 games IMO. Add Wade, Howard, Bosh, and Rose and it's a 4-3 type series in my estimation.
