What Putting Drills and Games do some of you like?
I'll start... Reaction Drill-- Line up three or four balls and putt them rapidly in succession to the same hole(3 to 4 footers). Don't give yourself time to think much. Do this several times until you start sinking them all without thinking much. This helps free people up who have started thinking of too many things. (Puggy Blackmon showed me this drill when he was Coach at GA Tech.)
