On this week's episode of GOLF's Subpar, PGA Tour caddy Joe Greiner joins former PGA Tour pro Colt Knost and jicky jack legend Drew Stoltz for an exclusive, in-studio, interview. The man on Max Homa's bag talks the advice he gave him at this year's Genesis Invitational, playing cash games with Phil Mickelson, Xander Schauffele and Charlie Hoffman, and who would come out on top in a caddy/player Tour event.
