I have some reasons for you.
1) LeBron almost beat the Celtics, even though he shot a pathetic %. Like MJ, Lebron constantly attacked the basket. This is something Kobe doesn't do. As great as Kobe is, he is still primarily a jumpshooter. LeBron, without a jumper and limited help, almost beat Boston. I think MJ, who was just as good as attacking...and has a jumper...and would have more help on LA's team than LeBron had with the Cavs, would have beaten Boston.
2) To back up #1, I have seen MJ light up the Pistons defense (which did zone him and beat the out of him when he drove). They couldn't keep him out of the lane. So no, I don't think a worse defense would have kept him out of the lane. I know you Laker fans need to overhype Boston because to make your spanking feel better, but the Boston defense is not the best defense of all-time. The 90's Knicks, 90's Sonice and 80's Pistons defenses that MJ beat were all better.
3) I don't see MJ letting his team blow a 24 point lead at home. How did Kobe play in that game? If LA wins that game the series is 2-2 with one more game at home. That game let Boston go up 3-1 and changed the entire series, especially since KG plays better when ahead and not when behind or under intense pressure.
4) When the Bulls were winning, MJ was able to get his mid-range jumper on anyone. The fadeaway was automatic. It didn't matter if it was in the face of 3 dudes...that midrange jumper was automatic. Kobe got plenty of midrange shots. He just missed them. I even saw Pierce block one (how often did you see MJ get his fadeaway swatted??). If Kobe was hitting his midrange jumper like he was against SA (who also packed the paint against him) then there is no problem. For whatever reason he was missing them this series.
Good enough for ya?
