You are conveniently leaving out Pierce putting up 41 in game 7 of '08 to match LeBron while Allen did absolutely nothing
Can you explain what this "leaves out"?
Boston was a monstrously better team then the 2008 Cavs. KG was 1st-team All-NBA, 1st-team All-Defensive, and top-3 MVP candidate that year, Paul Pierce was 30yo and also All-NBA and a Finals MVP in his prime, Ray Allen was a 32yo All-Star who set the NBA Finals records for threes that same year, and Rondo was a budding talent who outplayed all the Cavs' guards in that series.
Who gives a shyt if Ray had a bad series? Prime Paul Pierce with a stacked team still got completely outplayed by a 23yo LeBron with a scrub roster. The Cavs #2 option averaged 11ppg on 43% shooting and the series still went to the final minute of Game 7.
Hell, the Celtics had 4 of the best 5 players on the court and still only won cause PJ freaking Brown went 3-3 in the fourth including the biggest bucket of the game with 1:21 left and a 1-point lead.

and you are also leaving out the Cavs were favored by everyone to win that series in 2010.
That was because Boston had injuries during the regular season which made them look disappointing while the Cavs had LeBron playing out of his mind which hid everyone else's deficits.
Boston had 4 of the best 5 players on the court. True or false?
That's all there is to say on the matter. Nobody is impressed by LeBron and the Heat all in their prime beating the older version of the Celtics. KG was clearly not the same player after the '09 injury.
I told no lies so don't attempt to spin it.
You claimed Bosh was in his prime in the 2012 ECF when he was hurt and barely even touched the court the whole series.
You said that D-Wade was still prime in 2012-2014 but don't think that PP or KG were prime in 2010.
2012 D-Wade: Only plays 49 games, limping in the postseason, only averages 19-4-4 on 43% shooting in the Finals
2013 D-Wade: Only plays 69 games, averages 15-5-5 on 45% shooting in the playoffs and has to take a PLAYOFF game off to rest his knee.
2014 D-Wade: Only plays 54 games, averages 17-4-4 in the playoffs and 15-4-3 on 44% shooting in the Finals while not being able to guard anyone.
You claimed that THAT was prime Wade, but don't think that Pierce/KG/Rondo were in their primes past 2009 even though they were all making All-Star games all the way until 2012/2013. Come on now.
