The swings of greats such as Ben Hogan, Byron Nelson, Jack Nicklaus, Tiger Woods and Ernie Els may look perfect, but each features a number of flaws-- the same weaknesses that plague the swings of recreational players. If that's the case, then why do these golfers own championship trophies while you can't even make the A flight at your club championship? Is it because great golfers can overcome flaws by grooving them out? Not quite. The real answer lies in the ability of tour pros to repeat their flaws and effectively apply other flaws to compensate for the error.
