Could be early to say, but with covid-19 limiting play last year, it seems the bad teams have gotton worse. All the 15 point favorites seem to be beating their spreads but all hit the unders. Consider-
UCLA game
UTEP game
UAB game
. These week 0 and early week 1 games are showing a pattern. It could be reversed or it could continue. But my money is on the pattern continuing. The 15 point favorites with Unders greater than 56 points (average football game is 55 points) have all got my bet to hit the under.
