First Step useless for all O-linemen.
I know, I know, people are going to say it's a great SA, and I understand why they'd think that, but the reason it's a horrible waste of money and BTs is that it may fire off once every 3 games. You'd actually be lucky to have it work once a game. First Step is one of the spottiest skills for WRs, with most WRs not seeing any results until they take it up to 6+1=7 with equipment. ANY +SA piece that is actually already in your skill trees, save for the one that reduces holding calls, would be a better buy than a +First Step piece that will never work as you intend it to.
