I would follow jonpistone2, but it appears he is no longer posting here. IMO, there is no one better. His posted record speaks for itself, his history shows a rather big winner in every sport he posts, and as far as golf, well who even comes close. It seems that he is only releasing picks on Twitter now. I have no idea how Twitter works and had no interest in it until now.
There are some other good posters here, but it usually comes down to a personal comfort when following someone blindly. Also, for me, I do not like write-ups when I follow someone blindly, because a write-up makes me form an opinion, which may make me disagree with a pick, and when I'm following someone, I want to take my thoughts out of the equation.
IMO, if you do your homework, you should have no problem finding a winning forum poster here at Pregame you would be comfortable with to follow.
