Bryson DeChambeau, who emerged as one of the biggest stars in golf with three wins in 2018, is known for his scientific approach, including the use of single-length irons.
Former PGA Tour winner Brendon Todd doesn't think much of that innovation.
Instead of giving DeChambeau's clubs more attention, Todd encouraged people to focus on the "million" golfers who have won on Tour with clubs of different lengths - including himself, the winner of the 2014 Byron Nelson Championship.
DeChambeau climbed to No. 5 in the world rankings in 2018 while earning over $8 million.
Todd, who ranked as high as 43rd in 2015, has made three PGA Tour cuts since the beginning of 2017.
