I am hesitant to post this, not only 'cause I'm probably going to mush myself, but I really don't want to come across as bragging, etc.
Did it last year and am currently working on 8 straight, 10 of last 11. Majors only, tho, Bases, NBA, WNBA, College Foots, Pro Foots. I usually get dragged down by bases.
I do a higher than average number of season O/U wins and that has helped alot, along with using decent money management and control, never chasing, very very few teasers, limited parlays and generally treating seasons as marathons, not sprints.
Pro foots in doubt now, tho, as I am doing really lousy in my season wins picks. It is usually my strongest. Had GBay, Tam, St Louis, Chi and Denver figured totally wrong, and am going to need to get really hot to overcome that mess.
