The only way I'd want the answer to not be Coan is if you replace him with Pyne or Buchner. We need a good passing game.
If Tyree doesn't get 100+ yards or MTA doesn't get a sack and a half, I'm not in the least bit concerned about them moving forward, because they can still do work, even if it may not show up as much on the stat sheet.
But Coan's production is indicative to our success to becoming a more versatile offense.
