Much has been written in the annals of golf that Casper was the most underrated star in golf history, and the best modern golfer who never received the accolades he deserved. He was not considered one of the "Big Three" — Jack Nicklaus, Arnold Palmer and Gary Player — who are widely credited with popularizing and bringing enormous commercial success to the sport around the world; however, between 1964 and 1970, Casper won 27 tournaments on the PGA Tour, two more than Nicklaus and six more than Palmer and Player combined, during that time period. He is considered by many to have been the best putter of his era.
