If we can get one more starting o-lineman, and a WR or Defensive help (DT, DE, or LB), I think it's a home run for FA period. .... Keep in mind, we did already sign two potential starters before the open market: Long at guard--he was a decent started in Washington, I think he moves back over; and Williams as a possession, slot receiver type--of course he is a question mark, but the potential is there.
So far, it has been a very good off-season, with a chance to be better still.
