Rex Ryan’s emotions and ego will be tested on Thursday.

The Bills coach returns to his old grounds when the Bills visit the Jets in Week 10. Ryan led New York as head coach from 2009-2014. During his tenure, the Jets managed just two playoff appearances and struggled to finish above .500 in his last four seasons.

NFL Coaches Who Could Knock Out Rex Ryan

None of that, however, will be remembered. For every win and loss, Ryan provided an unforgettable moment to counter the team’s performance on the field.

Below are the most memorable.

Jets Making Calls To Replace Geno Smith, Ryan Fitzpatrick

Kiss The Rings

Ryan didn’t exactly get off on the right foot in New York. In a press conference prior to the 2009 season, his bombastic foundation was laid.

"I never came here to kiss Bill Belichick's rings," Ryan told a New York radio station.

He didn't arrive to beat Belichick, either.

One 2010 playoff win aside, Ryan finished 3-9 against the Patriots.

Teasing Rob Ryan

No one cared about Rex battling Rob Ryan in 2010 more than Rex himself. He made that abundantly clear as he teased his twin brother prior to their Week 10 matchup.

“Cellphonegate”

A picture is worth a thousand words, but this middle finger aimed at a Dolphins fan in 2010 cost Ryan $50,000.

Snack Time

No coach was made for TV more than Ryan. An uninspired practice in the summer of 2010 created the single greatest moment in “Hard Knocks” history.

The Guarantee

It’s been four years since the Jets won a Super Bowl. Correction: it’s been four years since Ryan guaranteed a Super Bowl and finished the season 8-8.
