Not trying to be a jerk, but this is a terrible idea/scenario. The draft is a crap shoot. Its always best to draft as many players as possible as opposed to trading picks to move up and draft "sure things". I can give hundreds of examples.......Dion Jordan comes to mind immediately.
If we draft Sewell at 3 (and I pray to God we dont), we can still pick up good players with those other picks. But drafting a LT in the 1st round simply doesn't make sense to me...
This is lame though. I can give you a draft counterpoint to nearly everything. For instance - Miami traded down instead of drafting Earl Thomas... and ended up with Jared Odrick + Koa Misi.
