hey agee not trying to tell you what to o but maybe try taking teams with smaller spreads as favs like un 9 this time of the year, it's that time of the year if a team is 10 + fav or higher they get back doored lot of times this time of the year in the last few mins like 2 mins or less. keep doing your work you will be fine, it sucks to lose late but you will be fine.
good luck you will get them this weekend.
