It's not just LeBron. They're getting excellent play from almost all of their role players - Mosgov, Thompson, JR Smith, Shumpert, Delly. Their defense has been good. They're making their open shots and knocking down their 3's at a great clip. They're winning the 50/50 balls. The last time I checked, when your role players are playing well in addition to your star(s), you're a good team.
They deserve a lot of credit, quite honestly. Especially since they're on the verge of a sweep in the ECF. But it's difficult to discount the fact that the East is undeniably weak. Downright pathetic really. Compare the paths between GSW and the Cavs.
GSW: NO, Memphis (arguably the 2nd best team in the entire league), and the Rockets (who deserve a lot of credit for beating a strong Clippers team that managed to knock off the mighty Spurs).
Cavs: A sub-500 team in the Celtics, an offensively-anemic Bulls team, and a banged-up and underperforming Hawks team.
No contest.
The Cavs deserve more respect than they've been getting, but they're a good team, not an elite one. GSW will win in 6.
