AHHHH BLOOOD BLOOOOOOD
There is a study just waiting to be done about whether players commit more personal fouls on red turf. It may also be justification in court for violent acts. "Your honor, I didn't mean to punch the man, but THE RED TURF WAS JUST SO METAL!" Judge: "I know! WHITE! WHALE! HOLY! GRAIL!" And then they jump on the bench and make air guitars and wailing noises, because red turf has that effect on people even in abstract discussion.
