I have been lucky to meet a bunch through a auto dealer chain I used to run. Everything from NFL, NBA,and NHL. Mostly from the tristate area Some off the top of my head. (I am a huge Rangers fan so pretty much all the players if/when I can)
Ewing
Kidd (HUGE douchebag, I cant stress to you what a dikk this dude was in person and on multiple occasions) Got to a point my boss wouldnt even sell him a Benz, because he didnt want him and his wife (At the time) coming there for service.
NFL
JPP
Eli (Nice dude, very funny actually)
Archie Manning (awesome guy, took pics with me and a friend, gave us signed mini helmets)
Brandon Jacobs, anyone in this area have met him hes always out and about. Dude has like an 900hp GTR that is crazy, he races locals. Beat my friends GSXR750 lol. He chills at Boom Burger a lot we were with him there for the last Pacman fight.
Cotchery when he was on the jets, I ran into him in a couple shady places we chill at in paterson. 1 night almost got into a huge fight with his people. He chills with this dude hes this skinny indian guy like 6'2'' 170, he loos/acts black, thinks hes tough shyt. He is one of the biggest pieces of shyt that you will ever cross paths with, one of those dudes that you can just sit back and watch how they act/treat people and you will want to choke him out without even talking to him. Cotchery swore he was the shyt and his boy was causing crazy problems, my friend was a bouncer at this place we were at and they tried to step to him, all hell broke loose. And this skinny indian prick quickly went from 100-0, quickly went to the back of the pile of people talking shyt, another friend grabbed him by the throat and everyone calmed down quick as hell
NHL
Graves
Brodeur
Lundqvist
Richter
Messier
Leetch
Jagr (One of the funniest people I've met, I wanted a signed stick from him, he went into his back pocket and pulled out a crossword puzzle he was working on, said finish it before we finish this fan night and I will give you one) I swear I finished like 12 of the 50+, (I was googling my ass off and still failed) lol He started to crack up but still had the trainer go get me a stick and signed it.
There are more, cant think of any good ones though
