awesome. seriously though, i was a two way starter, played MLB and guard, the best exercises for those positions for explosion are cleans, deadlifts and front squats. think about, coming out of a stance at those positions, almost the same movements as those. and since he is playing on the line, of course you need strong upper body strength for pass blocking and such, but the real difference maker is going to be close grip bench. think about it. hand positioning when pass blocking, run blocking. inside control. bull rushing,
where are the hand placements for drive? same position and movement as a close grip.
