Chamblee said it would be a Herculean achievement for Woods, who has won 79 times on the PGA Tour, to break Sam Snead's record of 82 victories.

"Looking at a 42-year-old, all things being equal, if Tiger was to win once it would be extraordinary, twice would be mind blowing. If he wins four times it would be one of the greatest things ever done in golf," he said.

Chamblee pointed out that behind Snead and Woods, the next 10 most prolific winners on tour－a list that includes Jack Nicklaus, Ben Hogan and Arnold Palmer－claimed only 14 victories between them after turning 40.

And those players did not have the chipping yips, something that Chamblee believes has afflicted Woods for three years and will continue to do so.

'Wall of doubt'

Chamblee expects Woods' long game to be fine at Torrey Pines, but suggested keeping a close eye on his work around the greens.

"It's not a matter of reps," Chamblee said, disagreeing with a suggestion that Woods is likely to improve his short game once he gets multiple tournaments under his belt.

"The yips start with bad technique and then it becomes a mental issue. Combination of the two is devastating.

"You're alone in the jungle and there's no path out. Nobody has ever overcome the chipping yips.

"Before every single chip he's going to hit this year, he's going to have to chisel his way through a wall of doubt."

Chamblee said Woods' chipping had been the worst of anyone in the field at the Hero in December, and counted seven times that he needed two chips to get the ball onto the green. Even before that, his chipping had been mediocre, he added.

Yet if Woods somehow replicated the greatness of his glory years, Chamblee does not think that today's top players would be able to compete.

"Tiger was the best of all time, by a mile," Chamblee said. "Tiger (at his best) would annihilate all the best players. If Tiger played the same golf he played in 2013 (when he won five times) he'd still beat them all.

"If he played the same golf as 2007, every one of them would spend hundreds of thousands of dollars on sports psychologists.

"I say this with due respect. Nobody thinks more of Rory McIlroy or Dustin Johnson than me. There's been a lot of great writers, but there's only one Shakespeare. And Tiger is golf's Shakespeare.

"In 500 years golf fans will still be talking about Tiger Woods."
