It's very possible.
I think the Lakers were more hungry than the Heat though. Kobe and Gasol weren't going to lose to Boston twice after '08. I don't get that same feeling from the Heat. The Lakers in 2010 were motivated by revenge more than anything. The games in Boston were close and you never got that feeling that the Celtics were just outclassing the Lakers. It was just better effort. The Spurs look like they legitimately figured how to neutralize the Heat.
But...the Heat have HCA. And that's huge. The role players will come back. The starts will perform as usual and they're in a familiar environment. Hard to beat.
Basically, 2010 was about revenge and payback for 2008 and the heats don't have that type of motivation to help them. I get the feeling this is either gonna be like the dallas series and they lose in 6 or the pattern will continue ending with the spurs winning in 7.
