I'm going to be in the minority here, but oh well...
Golden Tate is a classless punk. A lot of talent wasted on an asshole. If I were the coach, I'd fine him the maximum, suspend him for a game or two just to make him think about it, then demote him to 2nd string and make him earn his keep again. This is supposed to be a league of professionals, it's not backyard football.
The problem here is twofold:
1) Other players don't like that kind of crap. If it were me out there, I'd be gunning for him. I'd be looking to see just how hard I could hit him...and I'm certain there's a lot of players who feel the same way. He's gambling with a game, season, or possibly even career ending injury by taunting and acting like a jerk.
2) This is a team sport. But now everyone's going to be talking about what an ass Golden Tate is, because that's what made the highlight reels. It makes the team, the city, and the fans all look bad. And for what? So Golden Tate could act like a 15 year old for 10 seconds?
You're getting paid millions of dollars to be a professional. Act like it.
