OKC was the only legit team they played, and they got lucky against them because they were an inexperienced team that gave up monster leads due to poor execution, ball hogging, poor defense, and just being mentally weak. Just imagine if OKC was more experienced and didn't play like a bunch of young idiots, they'd have taken that series within 5-6 games max.
LA hasn't been good all season and continued their poor play in the playoffs, NOH with a healthy West probably would've won that series. You and others were overrating them just because they're the LA Lakers.
Portland was so good because Batum was on fire during the regular season, he was turning into a beast, knocking down shots from all over the floor with ease. Once the playoffs came it was back to reality for him, he was missing easy shots he made during the regular season, it had nothing to do with Dallas' defense either.
I just think MIA is much more different than these teams, more experience, better defense, 2 scoring options you can depend on an actual post scorer unlike OKC, etc.
Don't get me wrong, I think each game will be extremely close but imo MIA has enough to take it. And like I said earlier, there are going to be a load of calls going MIA's way.
