BTW, if anybody actually watched the Purdue / Minn game, holy moly did my faith in Big Ten refs take a hit.
The head ref who was the one talking to the crowd / TV to announce penalties had to go to the little TV to review a couple of plays, and because of the Michigan 1 second snafu, they are sharing those conversations live with the audience.
Purdue challenged whether a Minnesota receiver retained possession of the ball before going out of bounds (which was upheld). During the conversation with the Big Ten review center, the ref asked "So, the challenge is lost, that means they have one left right?" The Big Ten office said "Yes", to which the ref said "Should I tell them that, when I announce this?".
Seriously? Is this your first game as head ref?
Later, there was another review where there was another challenge, PJ was arguing for a better spot for his field goal kicker (2 yards), but lost the challenge because you can't use a challenge to check a spot, only to confirm whether a first down was made or not (which the receiver was well short of). The ref asked "So, the receiver did not make the line to advance, what down is it then?"
Really, you're the head ref and you don't know what down it is?
