I noticed that. He is clearly a Pats fan and he seemed to think they could do no wrong.
Onto the non-call, it looked to me he stuck his foot out trying to trip up the defender and the Bills player had to maneuver to not get hit or trip, in doing that he still fell but didn't get contacted by the Pats player.
Which is why they say it was a non call. But it still should have been called IMO, but anyway......
