We had a lot of issues with the PCO in a game on Friday. I asked, early in the week, for the PCO to meet with us pre game, but they had already had a game on Thursday and the PCO felt like he did not need a meeting, so he did not show up for the Friday game until 15 min prior to kickoff. Needless to say, we had major issues. Thursday crew was a good bit less experienced I guess and they informed the PCO that the 40 clock did not start until after the ball was placed on the ground and everyone had walked away. He also had no clue what the single hand pump meant. I sent word during the first qtr that I needed talk to someone that could get with the PCO and get it all right. At the half, my L went to the press box, in an attempt to get things straight. He even had the "cheat sheet" stating when the clock should be on 25, and the crew the night before told him totally different stuff. Needless to say, we had a lot of troubles.
