First off you're lying LeBron beat more than ten 50 win teams in the playoffs he actually beat 16 and by the time his career is over he will likely have beaten over twenty 50 win teams...
‘07 Pistons
‘11 Celtics
‘11 Bulls
‘12 Pacers (on 50 win pace in 66 game season)
‘12 Celtics (on 50 win pace in 66 game season)
‘12 Thunder (on 50 win pace in 66 game season)
‘13 Spurs (and the ‘13 Pacers had 49 wins)
‘14 Pacers
‘15 Bulls
‘15 Hawks
‘16 Raptors (and the ‘16 Hawks had 48 wins)
‘16 Warriors
‘17 Raptors
‘17 Celtics
‘18 Raptors (and the ‘18 Pacers had 48 wins)
‘18 Celtics
LeBron beat 16 teams and three of the teams he faced just missed the arbitrary cut by a win or two which means that number is close to 19 teams
And even those Nets and Wizards teams he went up against early his career had more talent than the Cavs on paper but LeBron was the difference.
In the Finals he competed against a 67 (twice) and 62 win team, he also lost to a 66 win Celtics and 64 win Pistons team and he defeated a 73-9 team he has faced some juggernaut dynasties in his career in ECF and Finals.
And no Utah and Denver would not make the ECF, those teams were never contenders and they never defended at a high level. The Spurs and Lakers made light work out of teams like that every year in the playoffs of that era. U can't point to a single that beat LeBron that wasn't an elite defensive team.
They weren't better than Cleveland, Detroit, Orlando, or Boston in that era.
Please enlighten me on how the '08 Nuggets were better than the '08 Pistons
Tell me how the '09 Jazz are better than '09 Magic
Man please the '09 Bulls or Hawks would give those teams legit series
