take a knee?

[SE Minnestoa Re]

I had a high school game many years ago where the offensive team told everyone they were taking a knee. The losing team just stood there except for one young man. He blew right through and just blasted the QB after his knee was down. We then proceeded to have to break up the brawl that ensued. I had a line judge punched by the offending player when he was trying to get him off the field.
