When you combine a guy who coaches a team from New Jersey with guys beating the crap out of each other for entertainment, you really shouldn't expect anything classy.
While attending a Strike Force mixed martial arts event at the BankAtlantic Center, the New York Jets' Rex Ryan ran into some Dolphins fans who promptly greeted the first-year head coach with a taunt of "Dolphins rule, Jets suck" -- a humble claim backed up by the Fins beating the Jets both times this year. Ryan reportedly replied with a "Go fuck yourself" and a middle finger. Whoops, it got recorded on cell phone cam and sent to 790 the Ticket.
The incident is being investigated by the NFL, and similar gestures by coaches have resulted in $250,000 fines.
