Do you correlate the SU win rate of your underdog plays when the spread is 8 points and below?
Just saying this because I follow the scores of games (both in the NBA and NCAAB) in which you play the underdog. I have no data to prove this but I believe you'd be better off just playing the ML on your dog plays.
Don't forget you had Thunder and Pelicans on the spread yesterday and both won SU.
