Anybody who watched basketball in the 90's knows Jordan dominated the league to a far greater degree than LeBron ever has (except for Ohio fans who should know it better than anyone but won't admit it because they're LBJ homers). You knew if Jordan was playing, the Bulls we're winning the title and there was nothing anyone could do about it. Jordan could have very likely won at least 8 straight titles if he didn't retire the first time, and maybe even 9 or 10 straight if he didn't retire the 2nd time.
Jordan also had way tougher competition in the East for most of his career. The 80's Celtics and Pistons, and 90's Knicks, Pacers, Magic, and Heat would probably have beaten either of LeBron's Cavs teams (not the Miami teams).
LeBron is amazing. There's a very good chance he might go down as the 2nd best player of all-time (still not there yet), but he'll never catch Jordan, it's too late for that. LeBron has had to many failures and times where he wilted under pressure to ever be considered better than Jordan. Jordan didn't run off to team up with someone else when he initially couldn't get past the Pistons, he simply worked harder until he could.
