They should be a top team but they are bound to have troubles this year. Their downfall could be their second unit. Their bench struggled during the pre-season, not to mention they only have one proven scorer in Jamison. Jamison however is one of the biggest scrubs I've ever seen on the defensive end. Hill's a fantastic rebounder but that's just about it from him. Meeks is a three point shooter but that's just about it. Blake hasn't been anything more than mediocre in his two years as a Laker. Outside of that, who do they have? Earl Clark? Chris Duhon? They were filler players in the Dwight deal.
They really dropped the ball when they got rid of Lamar Odom. He gave them a great edge as their sixth man.
Kobe, Nash, and Pau are all players who are getting up there in age, and while I'm sure they can create quite a lethal offense, their growing defensive inefficiencies, especially with Nash, who was never a good defensive player, could seriously kill them. Can Howard seriously cover for them. In Orlando, Dwight actually had some defensive talent. Peaches, Lee, Redick, Gortat all were passable to borderline elite defensive players. Howard was a centerpiece but those guys did help give Orlando a defensive edge. The Lakers do not have the same luxury as Orlando did.
They'll be amongst the elite, but until they find energy players that match up with OKC, they aren't getting past the Thunder.
