Jets coach Rex Ryan has struggled with the effects of dyslexia ever since grade school. "It was really frustrating," Ryan told The Associated Press. "So much of school, you have to write, but I just struggled. I couldn't help it." As much as 15 to 20 percent of the population has symptoms of dyslexia, according to The International Dyslexia Association. Ryan was diagnosed with dyslexia just a few years ago when his oldest son, Payton, was tested for attention deficit hyperactivity disorder. "They gave me a test, too, and there were like 100 words, not real words, but letters just thrown out there," Ryan said. "It might've taken me, I don't know, maybe 15 minutes to read it out. They brought in my youngest son, who was maybe 10 or 12 at that time, and he read it in like a minute. "The further we went along with it, the more I realized, 'Man, oh, man. I can see where I definitely had it."
