I'm 17 years old and just graduated from high school. I played football all 4 years and love the game and I was thinking about trying out for the Omaha Beef (an arena football team located in Nebraska). They have open tryouts but I know I am short to be playing safety. How fast/strong would you think I would have to be in order to have a shot of trying out when I turn 19? I'm already pretty strong (Nebraska Class A State Powerlifting Champion 148lb Wieght Class), but I'm not to fast (5.04 40 yard-dash electronic), and my vertical isn't to good either (27.5 inches). What should I try and lower my 40 to and get my vertical up to? Thanks guys.

Run every day.
