Your workout 2 seems a little excessive to me.

Also, as a linebacker I think your best benefits would be from raw strength and explosive power. With that I would suggest dropping the volume a little lower on your main lifts (squats, deads, bench). I also would suggest power cleans. They are an excellent lift (if executed properly) for almost any type of athlete. They develop explosive power and help develop a strong core which is great for transfering your power/strength to your opponents.

I am no coach so thats as far as I go. I will let some others help you with specifics on how to rearrange your routine.

Out of curiosity more than anything: Where are your lifts at in terms of poundages?
