Did they ever find out who was the guy in the smoke that tried to take out Arch?

Looks like the guy tased him.... or Arch is very sensitive to arm tackles

Looked like there was a camera man knelt down that he tripped over. Certain this meme will not be used later in the season though

yeah dude with the arm was trying to keep Manning from going down. He was the only person who knew what was about to happen.

Don't know, but I bet they'll be some adjustments made after that near disaster event.
