I think this season will ultimately come down to many things. I want to say this is not a knee-jerk reaction to the Miami game, but losing always put things in perspective...i must say though, these sentiments with me have been brewing for sometime.
I think the Laker's are clearing missing intensity...for several reasons.
Motivation. Health. Lack of Youth. New Editions. Chemistry Issues. Pick one.

There is a reason I was big on Sasha and Farmar. These two guys were energy guys; they are spot-up shooters; they are scorers. They put pressure on the defense. Farmar was an athlete/skilled player who could penetrate a defense and score the ball. (also finish the break) Sasha (and people forget this) had a 20+ points in that game 3 versus Boston in 2008. (he showed up and helped KB when nobody else did) More than that, the passion and intensity that Sasha plays with on both ends is something you cannot teach. (is something this team is sorely missing this year)
I like Blake's veteran qualities, and Matt Barnes is okay, but at the end of the day --- you can't teach youth or talent. Sasha and Faramr gave us that young talent and intensity that we sorely missed on Christmas day. I think a lot of teams make the mistake of parting with their youth after winning championships.
I hope I'm wrong, I hope Blake and co have a great impact going forward... However, I initially thought parting with Farmar and Sasha was a mistake, and I do fear it might come back to bite us..we have not established a potent bench all season..not like in the past.
