In doing a bunch of research into training for athletes, I've come accross a core set of principals. These core principals are; Get strong, get fast, and get conditioned. If you want to throw "Get Big" into the mix, then diet will be a major part of the equation.
As far as lifting goes, the basics still work the best. To get bigger, stronger, and faster, you want to focus on progression with the Big Boy exercises; Press, Bench, Rows, Deads, Squats, and maybe some explosive movements. You aren't going to see a lot of 350 lb linemen spending a lot of time on things like chest flyes and consentration curls.
