It's a trial by fire, but certainly they still want to win now. Mags was and probably is the better pass protector and probably has been a bit better at doing his assignments correctly, which is why he got out there.
I don't think the 6 OL thing is as much about getting another O-linemen reps as it was trying to find another player that can actually block. This goes for both the run and pass game. They were trying to simplify things for others (like the young TEs) and hoping that would help out the RBs a bit. It's had mixed results, as you well know.
