I agree with you about getting the touching right and missing the blocking. I'm not quite sure how those blocks were missed. I saw it the first time I watched the video where you can't even see the ball. I know it happens Amazingly fast, but you've got to be ready for that in that instance.
As for the 7man crews, but for the cost, I agree with you. 7 man crews "should" be better, but I don't know that they were in this instance. Maybe at other points in the game, the 7 man crew made things better, but here, where it's VERY important, it's a detriment. I still don't think the cost issue can just be ignored. Using 7 man crews during the regular season would improve officiating but I don't think the schools are willing to go there. Is there a compromise? If 7 man crews are only used on certain games, then are those officials deemed better than their colleagues? Since they have 7 man experience, do they automatically get the playoff games? I don't know about yours, but we've already got plenty of "superstars" in our chapter. They already dominate the playoffs. So, change all crews to 7 man? Some chapters would have trouble covering the games. And some crews would have a heck of a time filling the other spots with qualified (in the coaches mind at least) and available officials.
