So let me add on a little more to my OP. While it seems like neither did much, there was A LOT of pushing and shoving, clearly both were agitated throughout the game. They allowed the Jets to get into their heads. So while nobody "saw" was Dawkins did, it's very possible he had been warned that he was close to a flag, said something, and it put the refs over the edge. Same with Brown. The whole point of my statement was that they can't allow the other team to get in their heads - in this case it cost the Bills 30 yards, could cost more in the future. They have several other high level, high intensity games this year, are they going to be foolish and get more penalties?
