In a poll of the NBA's GM's the Lakers were picked to win the Championship this season. Off a trip to the Finals last season and the return of Andrew Bynum, anything less than a Championship will be considered a failure. The Lakers understand the expectations and embrace them. They even say it's the Celtics they want to beat in the Finals.
"Of course we want Boston," Kobe Bryant said. "When a guy you're fighting at lunchtime knocks you out, I'm coming back the next day. I'm coming back the next day and I don't want the little 4-foot guy. I want the big football player."
Sasha Vujacic has gone even further saying he's foregoing wearing green until the Lakers beat the Celtics in the Finals. Perhaps Vujacic is doing that as motivation but I think it's just to stop people from trying to steal his pot-o'-gold.
