I was tempted to just write "FOUR SUPERSTARS" and leave it at that, but I'll go a little further here.

This isn't the Lakers' big four. This is virtually the entire Lakers team minus Metta World Peace and Earl Clark. 

Yes, I still consider Pau Gasol a superstar. He can do extremely well when he has the post all to himself, as evidenced by his 25-point showing against L.A.'s loss to the Raptors. 

Meanwhile, the Lakers boast the league's leading scorer and rebounder. They have a player from this group in the top 5 in every major statistical category (points, boards, dimes, blocks, and steals) bar steals. They have the best shooting guard in the game today, the best center, one of the best foreign players, and the best pure point guard not named Rajon Rondo or Chris Paul. 

Yes, the Lakers have struggled, but this is more of a lack of a bench and depth beyond these 4 players and a horrible coach than their Big Four.
