Or to broaden the question a bit, I would like to know who everyone was who spoke to Pete about it between the time the play happened and when he threw the flag, and what they said to him.
From what I've heard, each team's booth people are privy to the same camera shots we are at home..........so in the 10 seconds it took Pete to pull out his challenge flag, who told him it looked worth challenging? Cause none of the camera angles we all saw showed even close to convincing evidence to overturn.
Again I think it went down like this:
Pete to the booth: "did AP extend AFTER he was out?"
Booth: "It sure looked like it live, but from the replays, hard to tell"
Pete: *throws flag*
