Is Bryson DeChambeau a good bet to defend his US Open title in June?
Golf's biggest hitter devised the perfect strategy to win at Winged Foot but will the kikuyu grass at Torrey Pines South derail his bid this time?
Brooks Koepka took the title with a very un-US Open score of 16-under at Erin Hills in 2017 but showed he could tough it out in the tournament's trademark brutal conditions when winning again at Shinnecock Hills with 1-over 12 months later.
After his dominant six-shot victory at Winged Foot in September, Bryson DeChambeau will be looking to become the eighth member of the back-to-back gang when he tees it up Torrey Pines in 2021.
But his record there as a pro doesn't seem to bode well for his US Open defence bid: he's played the Farmers Insurance Open at Torrey Pines twice and missed the cut both times.
Perhaps because of that questionable course form, DeChambeau is currently 14/1 fourth favourite with William Hill to win the US Open for a second year running.
The 27-year-old gave his views on several things, including Tiger's incredible victory on one leg at Torrey Pines in the 2008 US Open and the strategy he used to win the 2020 Open at Winged Foot.
But perhaps, in terms of him winning the US Open again this year, he left us with more questions than answers.

On what it takes to hit out of thick rough - something Torrey Pines is known for
"If it's ryegrass (the dominant strain at Winged Foot), that's a different situation. It could be down to the bottom, base level of the ground and you can still get it out for the most part. But pitching wedge or 9-iron, about 45 feet of loft for you to get it out and have enough ball speed to get the ball up to a green.

Recently, Rory McIlroy made headlines for saying that trying to be like Bryson and smash the ball greater distances had had a detrimental impact on his game.
In which case, Torrey's kikuyu could be this particular superman's kryptonite.
