OK, I'll chime in again.
To me, Tiger at his best has always played the game backward. He knew he could get away with all manner of poor play from tee to green, because he could always count on his putter and short game to bail him out. No one (maybe Mickelson on his good days) can hit the kind of all-world recovery shots Tiger can, and he hit them because I think he always thought either: "I got this shot," or "I don't care if I miss this, because I can get it up and down from anywhere."
On occasion, he showed the kind of course discipline and management that Jack was well known for, notably at Hoylake in '06 when he sort of bunted his way around the fairways, hit a ton of great approach shots, and sank a bunch of putts to go low there (-18). But even that approach was predicated on his belief that he didn't have to bang his way around the course, because he figured if he hit greens, he'd make enough putts to win. And he did.
I've never really thought Tiger was a streaky putter; he sank pretty much anything he wanted to from '99-'07, and was great in the clutch in '08 at the US Open against Rocco (Mickelson to me is the definition of a streaky putter). But he hasn't putted nearly as well in the past two years, and what's really been his downfall is his magical short game -- that to me has been his chief culprit, and why he hasn't won any majors since June of 2008. He'll always be wild with his driver, he remains probably the single best iron player in the game, but his margin for error is alot thinner than it used to be, because he's not consistently as good of a putter as he once was, and his ability to get up-and-down for par/birdie has really gone south. No one -- ever -- has had the short recovery game of Tiger in modern-day golf; now he seems pretty average, or slightly better than the field.
