I've said this before, but the 2011 Finals are very different. The Heat were big favorites, LeBron was in his prime and they got beaten convincingly by a team of Dirk, Jason Terry and Tyson Chandler. Not only did they get beat, but LeBron was TERRIBLE in the Finals, like almost unfathomably bad given how great he has been since. 17-7-7 as the best player in the world, and getting legitimately outplayed by Terry in the last few games. LeBron scored 8 points in Game 4, a game he played 45 minutes in and the Heat lost by three.This is like Tom Brady vs Joe Montana. You're awarding greater credit to losing before the Finals than you are to making it to the Finals and then losing to the champs. Jordan went 6-0 in the Finals but failed to make it there on another 7 occasions. Montana went 4-0 in super bowls, but had plenty of other uglier, earlier losses.
Jordan never lost a series his team was heavily favored in. Even if you want to talk about the 1995 playoff loss to Orlando, Jordan played really well even though he had only returned to the NBA with 17 games left in the regular season, going for 31-6-4, and Orlando was a more well-rounded team and the Bulls had to guard Shaq with Luc Longley.
When comparing 6-0 in the Finals to 3-6 in the Finals, and comparing 6-3 in the Super Bowl to 4-0. In both cases, the obvious choice is the person who won more titles, which is why Jordan and Brady are the superior options.
