I'm going to pile on @TommyRude.
The more I think about this take the funnier it gets in my head.
Colin Montgomerie lost at least three majors down the stretch that I can think of.
1994 US Open shot 78 in a three-person-play-off losing to Ernie Els (and Loren Roberts). Montgomerie pulled drivers left and pushed them right the entire play-off round.
1998 Masters; pulled three of his last five approach shots left. Ended up finishing tied for eighth.
2006 US Open was tied for the lead (with Phil). He was sitting in the middle of the fairway on 18. Hit his approach short, pulled his chip shot long left, 3 putted.
Therefore clearly, Colin Montgomerie's reliance on bulky musculature and overly testosterone driven attitude obviously caused these issues. 😁
If you want to go the other way, I know Brooks Koepka has credited all five of his majors to the fact that he's powerfully built. ... I'll suggest DeChambeau may say the same thing.
