True, 6-0 trumps everything. But LeBron has made 6 total finals with lackluster teams (except when Wade and Bosh were healthy). Jordan took awhile to even make the finals and it wasn't until his team was pretty stacked. 5 in a row counts for something.
The quality of Jordan's teams have just as much to do with his titles as MJ himself did. You don't think those same Bulls teams with MJ would've also won 6?
