Obviously, it's entertainment and with the money being shelled out for tickets, organizations feel the need to turn your experience from a game into an event. But, do we really need guys in orange shirts patrolling the aisles chanting "defense?" And, guys walking up to you mid-possession asking if you want your photo taken?
Bill Simmons has written on the select few crowds that know how to truly have an influence on the game, with the Spurs and Blazers crowds being the best at it in his opinion. But, in the 90's, the Garden crowd did the same, they (as my friend puts it) "knew when to pick the team up, and knew when to put the other team down."
