I used to coach JV golf at a local high school. Once a year I would make the guys play 9 holes with one club and a putter. Inevitably, every year, one of my knuckleheads would shoot a 41 or 42 with one club and a putter, and the next day in a match would shoot 45 or 46 in a match with 14 clubs. A-a-a-a-a-a-ah!
LOL. Is that b/c they used the clubs they have not practiced much? Next time, make sure he only take 2 clubs to a match.
