There is no other sports city in the country, where a player from a different team can interrupt a preseason practice to shake some hands and throw a ball around. I guess Rondo is at that level where he can break up a Belichick practice and get away with it. Not sure why, but when two Boston teams mesh and interact with each other, it creates a unique spectacle. Like they shouldn’t be getting along or something. Similar to Amy Winehouse and vitamins..
