Who is THE main character in Entourage?

me and some friends constantly argue about this. I understand that there are 4 main characters. But which one, in your opinion, is really THE main character?

I would say the main character is Vince Chase. Although they have really done a great job developing the characters, the show is about the rise and fall of Vinny Chase. If he wasn't there, there wouldn't be an Entourage. He just has an awesome supporting cast!

i would also go with Vince Chase
