Yeah, I wouldn't say Lamar Jackson was robbed. It was close between him and Josh Allen all year. Allen's stats were pretty impressive, too. Yes, Jackson's stats were better, but it's not just about the stats. Allen didn't have Jackson's receivers or Derrick Henry.
And voters probably thought, Jackson already won it a couple of times and poor Allen's been so close before. (And really, Mahomes is still better than both of them.)
I probably agree more with your statement that Dan Quinn was robbed, but Kevin O'Connell did a pretty good job this year as well. When the votes were cast, we didn't know that the Vikings would get knocked out in the first round and that the Commanders would get to the NFC championship game. But no matter how you look at it, Quinn's job in Washington was truly impressive. Makes me wonder what he would have done in Seattle.
