Every Sunday night, the editorial staff of the SI Golf Group conducts an e-mail roundtable. Check in every week for the unfiltered opinions of our writers and editors and join the conversation in the comments section below.
1. The weekend leaderboard in Canada featured several Americans who could fit the bill for "best player never to have won a major," including champion Brandt Snedeker, Matt Kuchar and Dustin Johnson -- and before his withdrawal, Hunter Mahan. Which of these four players is most likely to break through in two weeks at the PGA at Oak Hill?
Alan Shipnuck, senior writer, Sports Illustrated: Sneds. He has an extra gear that these other dude don't possess. It's too bad his season was interrupted by a rib injury because circa Pebble Beach he was playing incredible golf. But clearly he's back on his game and a great putter who's playing well tee-to-green can tame any golf course, even fearsome Oak Hill.
Michael Bamberger, senior writer, Sports Illustrated: The order for Oak Hill is Kuchar, Mahan, Snedeker, Johnson. The order for career titles is Johnson, Snedeker, Mahan, Kuchar.
Gary Van Sickle, senior writer, Sports Illustrated: Oak Hill is a tough driving course that's long for amateurs but not so much for the pros. The rough and the trees aren't usually playable. When in doubt, go with the best putter. That's Snedeker, and he's hitting it well at the moment, based on the Canadian Open.
Jeff Ritter, senior producer, Golf.com: All four of those guys are due, but I'll take Mahan, who's played in the final group on Sunday in two out of the season's three majors. Plus, after leaving Canada to be with his wife during the birth of their first child, karma owes him one, doesn't it?
Joe Passov, senior editor, travel, Golf Magazine: Snedeker showed a lot by coming back from a rare show of frustration -- his 79 in round 2 at the Open. He's putting so well, he's got to be a favorite whenever he tees it up.
2. Dustin Johnson had a piece of the lead Sunday before imploding with a triple bogey on the 17th hole. D.J. has more PGA Tour victories than any other player under 30 (he's won seven times), but do you still consider him an underachiever?
Bamberger: I really don't. He doesn't think his way around a course with ruthless efficiency, and that's a golf skill along with all the others he has. It's a skill you can learn and I imagine he is.
Passov: Yep. Underachiever so far. So close on so many big stages on so many occasions. With his length, touch and the ability to play hard courses well, he should be good for three wins a year -- and the occasional major. Hasn't happened yet.
Van Sickle: It's unfair to call D.J. an underachiever. He's an achiever. Does Rickie Fowler or Hunter Mahan have seven wins? Didn't think so. Johnson may or may not ever land his major. He's got the power, but there's more to golf than that. Maybe he's the George Bayer of this generation.
Shipnuck: It's a nice career so far but D.J. has always been content to coast on his prodigious natural ability. If he applied himself like Sneds has, Dustin could easily be No. 1 in the world, or damn close to it.
Ritter: It's hard to forget D.J.'s final-hole rules gaffe from that fairway bunker at the '10 PGA, along with his other blunders and missed chances over the years. He's had a nice start to his career, but it could be so much more.
