People that say its more pressure to play for the Lakers subscribe to the theory that other teams dont set high expectations and demand excellence. I find that hard to believe that the Lakers are the only team that has that expectation.
I'm not going to say that other teams and their fans don't demand excellence, but it's not the same level of excellence. Other teams hang Division Championship banners and Conference Champion Banners, the Lakers only hang NBA championship banners. Nothing else is considered good enough.
With the difference between the number of championships that the Lakers have vs. other franchises (except Boston) there is obviously something different about the Lakers vs. other teams.
