I wouldn't count LA out just yet. They were down to games against an equally strong San Antonio team, and they came back to win the series. Both teams played excellent defense, think you can make an argument that LA can make a comeback here.
Anybody else's team, it would seem farfetched. Your talking about an experienced Laker team, if they get the hunger, they can do it. Detroit has been known to be inconsistent in the previous rounds too. I say LA.
