Bills quarterback Ryan Fitzpatrick has been working with coach David Lee on his throwing mechanics this offseason. The quarterbacks coach is known as a master at fixing flaws in passing mechanics. "I was expecting that," Fitzpatrick said. "I knew that he was a technician and a hard worker. Everybody told me about his work ethic and how passionate he is about football so I was excited for it. "He's a big proponent of just being able to throw with your lower body. Sometimes when you get closed off as a thrower with your front foot in terms of where it's pointed where you can't get your hip through and use your legs it becomes a throw with all arm and you lose a lot of power."
