"DeChambeau headed straight from post-round media duties to the driving range as he sought to resolve his issues. As he did so, Cobra fired back. The manufacturer’s tour operations manager, Ben Schomin, is heavily involved in the design of DeChambeau’s equipment and told USA Today: “Everybody is bending over backwards. We’ve got multiple guys in R&D who are CAD-ing this and CAD-ing that, trying to get this and that into the pipeline faster. Bryson knows it. It’s just really, really painful when he says something that stupid.”
DeChambeau’s driver is 46 inches long and has just five degrees of loft. “He has never really been happy,” Schomin said. “Like, it’s very rare where he’s happy.
“Now he’s in a place where he’s swinging a five‑degree driver with 200rpm of ball speed. Everybody is looking for a magic bullet. Well, the magic bullet becomes harder and harder to find the faster you swing and the lower your loft gets.
“It’s like an eight-year-old that gets mad at you. They might fly off the handle and say: ‘I hate you.’ But then you go: ‘Whoa, no you don’t.’ We know as adults that they really don’t mean that and I know that if I got him cornered right now and said, ‘What the hell did you say that for?’ he would say that he was mad. He didn’t really mean to say it that harshly. He knows how much everyone bends over backwards for him. But it’s still not cool.”
