You're looking at this out of context. The 50 win Thunder were about as tough of an 8 seed as it gets. Someone pointed out earlier that the 01 Lakers didn't face a single team with less than 50 wins, so why are we going to ignore that exact same situation all of a sudden?
The Celtics weren't a joke dawg. Perkins impact on that team was pretty damn minimal compared to the rest of the starters. They were closer to the 62 win team from the year before than they were to the 50 wins they had that year. They beat a 61 win team and a 59 win team themselves in the playoffs, and you're just gonna ignore that shyt? Once they got to the playoffs, they became dangerous again. And the Lakers had to beat them with their backs against the wall. You're delusional if you think anything about the 2010 Lakers road to the Finals was easy
I don't give a crap who the 8-seed is.
Sure, the #8 Thunder were a good 8-seed, but they were still just an 8-seed, and they weren't a contender. They had been 23-59 the year before, hadn't added any experienced vets, and were making the playoffs for the first time ever. They weren't ready yet, so I don't really care about them at all.
The 53-win Jazz, led by Deron and Boozer with Mehmut Okur as the #3 scorer, were NOT scary either, and the Lakers swept them.
The 54-win Suns were 35-year-old Nash, 37-year-old Hill, Channing Frye, J-Rich, and a declining Amare. That team never made the Finals at their peak, and we're supposed to be scared of them as a contender when they're

?
And then the 50-win Celtics in the playoffs. Yeah, when healthy they were better than 50-wins, but the Lakers DIDN'T beat them healthy. The same thing happened in the Finals that happened all season - when all five starters were on court and engaged the Celtics were world beaters, whenever just one guy got hurt they were vulnerable and exposed. You say that Perkins didn't matter but the Lakers only won because they outrebounded the Celtics 105-79 in the last two games and out FT-ed them 56-27, and still just barely won. Rebounds and FT's were nearly even the first five games, take out the big guy in the middle and suddenly the Lakers are doubling up the Celts there?
The teams the Mavs beat the next year were FAR better. They had to beat a decent Portland team, a more experienced version of that Thunder team, a Miami team that handled the Celtics healthy....and those same Lakers. How is that not objectively far more difficult a path than what the Lakers faced?
