Jennings or Colston right now would get it.
I know this has no chance realistically, but I think McNeill for the Chargers deserves mention, if not the award. He's a rookie, was projected as a RT, playing LT (arguably one of the toughest spots in an offense) and doing a pretty good job. Rivers has been sacked 5 times in 4 games, and faced some pretty good defenses. 4 of his sacks came last night, but that offense line as a whole adjusted and found a way to protect Rivers and let him open up that offense. Sure, ESPN and the NFL won't acknowledge, but a rookie playing LT well is probably going to make the most significant impact on offense for any team.
