When Brandel Chamblee tipped Scottie Scheffler to win the PGA Championship at Aronimink earlier this week, it seemed like a safe bet. After all, the world number one has been on a tear this season, racking up a win, three runner-up finishes, and six top-5s on the PGA Tour. But in the world of elite golf, even greatness can draw scrutiny—and Scheffler's so-called "struggles" this year are a testament to the impossibly high bar he's set for himself.

Through two rounds at the PGA Championship, Scheffler has shown flashes of brilliance and moments of grit. He opened with a solid 67, then battled through a tougher Friday to post a 71, leaving him just two strokes off the lead with 36 holes to play. It's a position that keeps him firmly in the hunt, but the question on everyone's mind is this: does Chamblee still believe his pre-tournament prediction will hold up?

Speaking on The Golf Channel's Live From The PGA, Chamblee didn't hesitate when asked if he's sticking with Scheffler or eyeing someone else to hoist the Wanamaker Trophy. "I mean, as we're sitting here, he's just two back," Chamblee said. "I still don't think we've seen Scottie Scheffler's best golf yet in his career. He still has a propensity to miss some short putts, and this year, his irons haven't been particularly sharp."

But here's the thing about Scheffler—and why Chamblee remains bullish. The former PGA Tour player turned analyst highlighted a specific skill that sets the world number one apart, especially under the pressure of a major. "This is why you want to see tests like this," Chamblee explained. "You want to see the best players in the world actually tested. You want to see them have to do things that are just mind-bogglingly difficult, that very few players can do."

Chamblee drew a fascinating parallel to the game's all-time greats. "Why do major championships test the best players? The course is firmer, the greens are firmer, the rough is thicker. Is it any surprise that the two greatest major champions of all time—Nicklaus and Woods—were phenomenal out of the rough? Why? Because they had upright swings."

For Scheffler, the weekend at Aronimink will be a true test of that championship mettle. Two strokes back, with a game that hasn't quite clicked on all cylinders, he's still right in the mix. And if Chamblee's instincts are right, we might just see Scheffler rise to the occasion when it matters most. After all, it's in these mind-bogglingly difficult moments that legends are made.
