Every golfer steps onto the course aiming to compete under fair conditions, but U.S. Open champion Lucas Glover revealed - that might not be the case!Speaking on his SiriusXM PGA Tour Radio Show, Glover shared a blunt realization:"I came to the realization that we're not all playing under the same umbrella at these majors unless we did test everybody." His comments came in the wake of one of the biggest controversies of the month—the USGA's driver testing during the 107th PGA Championship.Before the Quail Hollow event started, Rory McIlroy's driver was tested and shockingly declared "non-confirmed." But instead of addressing the growing debate, McIlroy stayed silent, skipping media duties throughout the event, fueling speculations.Recently, McIlroy opted out of the Memorial Tournament, an event he had attended consistently for the past eight years.Meanwhile, Scottie Scheffler, the PGA Championship winner, faced a similar issue.His driver also failed testing, forcing him to switch clubs, but unlike McIlroy, Scheffler spoke openly, diffusing much of the speculation before it could spiral out of control.But that did not deter Glover, who was not convinced by how selective testing was applied, questioning whether players were truly competing under equal conditions.Lucas Glover reveals how players cheat driver testFor Glover, the problem is not just isolated incidents—it is an inconsistency in testing across major tournaments."I've been trying to think all morning and all day how to say this without sounding like it's gonna sound, but most guys don't give them their real driver anyway. They hand over their backup so it won't fail testing. It's their way of protecting the driver they actually use.""I know a lot of guys, they keep two drivers in their bag just in case. 'Hey, oh, yeah, it's this one. It's this one right here. Yeah, do this, test this one,'" he revealed.But the issue is bigger than just the players themselves. The lack of consistency in testing players' drivers and putters puts things on an unequal footing."We got LIV guys, we got other tour guys, we got tons of different players and tours being represented at the four biggest tournaments of the year. "So why doesn't everybody get tested at every major? And why don't we somehow try to make sure it's the driver being used?"His solution? Universal driver testing for all players at every major event to eliminate loopholes."If that costs X amount of dollars, great. Let's do it," he said. According to the US Open champion, these organizations "got plenty.""Look at the tents they build every week. If we're going be on an equal playing field, and the four biggest events are going to bring all these people and all these tours together, let's make sure we're playing under the same rules." he expressed.Glover's own experience with testingUnlike McIlroy and Scheffler, Glover was among the few players whose driver was selected for testing, and he passed without any issues."I don't hit far enough to thin a face out anymore," he joked. "But mine was fine."Had his driver failed, Glover admitted, "I'd have been devastated."Switching drivers, even if they are the same model, can significantly impact a player's performance, which is why he sympathized with McIlroy's situation."I found out a couple days later, the next day, whatever it was, that that was an entirely new driver""And I said, wow, that stinks for him because you gotta drive it there [Quail Hollow] really, really, really well. And obviously, coming off the Masters and coming off playing great all winter, all spring, and you gotta do that. Yeah, I was like, man, that's tough."With McIlroy's silence to date, the debate over driver regulations is now front and center.
