Reddit mentions of Play Like You Mean It: Passion, Laughs, and Leadership in the World's Most Beautiful Game

This is really an unfortunate thread, because I have the distinct feeling that I'm feeding a troll now. Rex Ryan might actually be the perfect coach for you because as he says, "I may not be right, but I'm honest."

The only one here making baseless assumptions is you.
Did you forget the Jets were on "Hard Knocks?" In this article he describes how he wanted to show off his brand of football and was expecting it would get people excited about the Jets.
Part of that brand was playing mind games with his players. He had center Rob Turner pick a fight with Vernon Gholston to test Gholston's toughness.
He also got into a shouting match with the starting linebacker of the Dolphins before his first game as a head coach.
Here is a list of bravado from his first year as head coach, if you are interested.
Maybe the sources are old, so how about him punching a wall behind closed doors, before a post-game press conference this year.
Rex Ryan is anything but fake and says as much in his book.. If you don't believe him how about his players.

If forced to provide evidence for my opinion I would cite that material because it is available to both of us. Moreover, from the coaches in High School/College, that I talk to, who've either went to clinics and met him or worked with him at some level, or the NFL/College officials that I know pretty well all say the same things, that Rex Ryan himself says.

He is honest, genuine, passionate, bold, outspoken, brash, and will do whatever it takes to motivate and win.

That appeals to a lot of people, I get it. From the comments in your post I can tell you are a passionate person too, maybe that is why you run to Rex Ryan's defense, as though he needed it, because you see a kindred spirit.

But, I prefer the calm, relaxed, quite, mature, private, businesslike confidence Mike McCarthy & Co. have been cultivating for some time. The relax approach certainly looks like the one that has been able to sustain a level of success, relative to the rest of the league. It also smacks more of New England's staff than of New York's.

I'm not a Rex Ryan expert. I don't know him personally, but I'm trying to be as informed as possible when commenting and add value to conversations. Your poorly focused and unlettered response tells us to admit we can't know a person's real attitude, when Rex Ryan purposefully makes an effort to reveal his attitude to his players, and the media (remember the access he had given to HBO and his reasoning for it). His personality is one of the reasons players appreciate him so much. He is a real person, in addition to being a good coach.

Again, regardless of his credentials as a defensive mind, or our ability to truly know the man behind the sweater vest, in looking at the examples of manipulation, public humiliation, and hubris he engages in, they all seem to me the antithesis of a Ted Thompson or Mike McCarthy hire, he doesn't fit the culture in Green Bay.
