Excellent point made by dd, about how the 4 is a better post today with random posts than it was in the past with assigned posts. My buddy Mark K loves the 4/123/123, but I haven't had a lot of luck with that bet. When I like the team in the 4 hole, I'll typically look for three other teams I like to play under them, in somewhat sensible posts. I've hit a good number of trifectas using 4/126 or 4/127.
