I've never liked Tiger but it would have been nice if he showed up today and made the back 9 more dramatic.
So much of golf comes down to just breaks of the bounce or roll, and then of course what you do with them.
Phil had a short par putt on 14 do a 360 around the hole before falling in. A bogey there moves him to +1 and perhaps puts him in a worse place mentally - instead that was the last bad shot he hit of the day, really. Then, as Phil is closing, Tiger is four holes back. Tiger puts his approach on 14 a foot from the hole for a birdie to move to +1, right after Phil"s birdie on 17 had him -2. Then, Phil has his approach on 18 come within a foot or two of going in the greenside bunker, but gets a good bounce and roll and closes with a birdie to really wrap it up. Tiger hits a great approach on 15 but it chunks into the ground in front of the green instead of bouncing up. That bad break turns into a bogey when he chips 10 feet past the hole.
I want to say those two shots were within a few minutes of each other. Give Phil a tough lie in the bunker, and maybe he finishes -1 (although you'd have to think he saves it with a good lie). Have Tiger's ball bounce on the green to a makable putt and maybe he's E. Then his birdie butts on 17 and 18 mean something.
Of course, Phil was playing better golf and took advantage of his breaks and shrugged off his bad ones - he clearly got a bad break on 16 when his ball rolled off the green and still got his up and down. Tiger on 15 knew he was at least 3 shots back and was probably trying to hole his chip, and a bad shot ended what slim hopes he had. But he was still very much relevant on the 15th hole - and a great close made everyone irrelevant down the homestretch. If Phil just shot an excellent 69 instead of a ridiculous 66 (best final round in a major since 2000), the whole finish is dramatic - because everyone in contention was +2 to +4 on the day.
