Ryan has become one of those public figures people either love or hate with very little middle ground. Here are the top 10 trash-talking moments in the career of the current Jets head coach.
Almost immediately after receiving the New York Jets head coaching job, Rex Ryan looked to ignite the fire in the Jets' AFC East rivalry with the New England Patriots.
In an interview that summer on WFAN radio in New York, Ryan explained that he, "never came here to kiss Bill Belichick's, you know, rings."
This was the first of many shots that Ryan has taken at the Pats and their head coach over the past few seasons, doing his best to get his football team out of the shadow of the three Super Bowl rings their New England rivals have won over the past decade or so.
The week before Rex Ryan's Jets played against then-defensive coordinator Rob Ryan's Cleveland Browns team, Rex decided to give the media another angle to approach the brother versus brother storyline.
During a press conference, Rex opened up by giving a rundown of the team's injury report, before walking off the podium and coming back dressed as his twin brother.
Now, this moment wasn't meant to take a jab at Rob, but simply a light-hearted joke from one brother to the other. This may not be Rex's biggest trash-talk moment, but it is one of the funnier press conferences he's had.
The New England Patriots and New York Jets found themselves in a Divisional Playoff game against one another last season, with yet another bold proclamation from the Jets' head coach.
Rex Ryan told anyone who would listen that his team was going to defeat their AFC East rivals that Sunday, and to the surprise of many, the Jets were able to pull off the upset.
The outspoken head coach called that playoff game the "second biggest game in franchise history" and was able to deliver a win.
Before playing against the Baltimore Ravens in Week 4 this regular season, Rex Ryan took a small jab at his old team.
Ryan explained that the two teams had talked about the possibility of meeting up in the AFC Championship Game this season, to which the Jets' head coach had a few choice words for Baltimore:
"Now we haven't won an AFC Championship Game, but we've gotten there two years in a row. The Ravens haven't. So you can throw that one right back at them as well."
While these were big words coming from the former Ravens defensive coordinator, head coach John Harbaugh's team was able to secure the second overall seed in the AFC while Ryan's Jets will be watching the playoffs from their television sets.
Before the 2011 season even began, and amidst all the flurry of free-agent signings after the lockout, Rex Ryan had a little more to say about the New England Patriots.
High off his team's 2010 AFC Divisional Round playoff victory against their hated rivals, Ryan stated this in an August press conference:
"I think we have to find somebody out there to beat New England besides us, I think that would help. Anybody out there want to sign up for it? Are you good enough as a team to beat the New England Patriots? I'm challenging the league."
In that same press conference, Ryan gloated about the fact that, in the 2010 season, only the Jets and brother Rob Ryan's Cleveland Browns defeated the Foxborough-based powerhouse.
Before the Week 16 showdown between the New York Jets and New York Giants, both teams threw some trash-talk back and forth.
Ryan made one of the more bolder statements of the week leading to the game when he called the New York Jets, "the best team the last two years."
The Jets' head coach backed up his argument by pointing out that Gang Green made the playoffs both in 2009 and 2010 while the G-Men were on the outside looking in.
The Giants had the last laugh on Ryan and company, however; Big Blue not only knocked off the Jets that week but were the only New York team to make the playoffs this season.
Sticking with this Week 16 matchup, Ryan had a little more to say about his NFC rivals.
Ryan made headlines when he said he doesn't want his team to be viewed as the New York Giants' little brother, which is the way many New Yorkers view the Jets.
This statement is one that may be a bit controversial by Ryan, but it's one that should make his team feel confident their head coach.
The son of Buddy Ryan is never going to keep his mouth shut, but at least in this instance he was attempting to shed light on his team's recent success and the Giants' struggles.
Just one week after the Green Bay Packers won the Super Bowl last season, Rex Ryan stirred the NFL pot once more.
While attending an NBA game between the Los Angeles Lakers and New York Knicks, Ryan took the time to explain to the New York Post that, "There's no way [the Jets] don't get it next year. Next year I know we'll win it."
Ryan was unable to deliver on his Super Bowl promise this season, but he certainly got people talking with that comment.
In just his rookie season as head coach of the New York Jets, Rex Ryan publicly joked about planning his team's Super Bowl victory parade in New York before even playing AFC juggernaut Indianapolis in the 2009 AFC Championship Game.
Ryan made plenty of bold proclamations in his first year and has continued to do so, but perhaps bit off more than he could chew when he essentially dismissed Peyton Manning and the Colts that playoff season.
The Jets would lose the conference title game by a score of 30-17, with running back Thomas Jones posting just 42 rushing yards in a game where nothing went as planned for the mouthy head coach.
Now, this trash-talking moment wasn't the most publicized on the list, but it was one that was a bit out of the ordinary for Rex Ryan.
Perhaps learning from his mistake against the Colts the previous season, Ryan didn't give the Pittsburgh Steelers much bulletin board material before their 2010 AFC Championship Game.
Instead, he turned his attention to his own players.
Ryan was quoted by USA Today saying, "If you can't get motivated to win an AFC Championship Game, I don't know what else you need."
There have been a few times where Ryan called his team on the carpet for losses, but this time we saw him attempt to motivate his team not by bragging, but by challenging them. The Jets were unable to answer the call and lost to the Steelers that Sunday by a close score of 24-19.
