I'm not worried about the recent leaks to the press about his medicals. This is Lying Season -- who knows what to believe? One thing I do know: Jack is a stud who can play all three linebacker positions. In fact, he's so athletic and versatile that some project him to be a safety in the pros. His style screams for Bradley's defense. Jack would give the Jags' D some needed sizzle and talent in a huge season for the Bradley/David Caldwell regime in Jacksonville.
