Dude, it's not that the refs care; it's that they're being told what to do and when; by Vegas Betting honchos. As an individual game develops, betting keeps happening so odds keep changing by the minute. Don't you think it's a little strange that these crucial late-game flags suddenly start appearing in critical moments? Please, someone convince me the refs are not hearing someone in their earphones telling them to throw a flag on this next play or that next play. As someone said earlier - a flag could be thrown on almost every single play. So Now that betting is totally legal, and encouraged, I don't think games are necessarily pre- 'rigged', but they most likely ride on constantly moving betting up until very late in the game....
