Tiger is rusty and when he gets it going he is not going to be as good as he was, but he will be good enough to win 5 or so more tournaments and show up in a major once a year over the next few years. I don't think he will win another US Open if they stick to these traditional setups like they have this week. His best shot at another major will be at The Open and The Masters imo. Especially The Open it just seems to favor experience over great ball-striking. Either way I just enjoy watching him out there. DJ is super good, maybe the closest to Tiger that has been on tour. He has all the shots and I think he doesn't care enough to get bothered by bad shots. He is just out there playing golf for a living. Win or lose he gets another check and moves on.
I like the US Open when it plays like this. It's cool to see who can make the least mistakes rather than who can make the most birdies. Golf Digest has an excellent article about this course and setup exposing the golfers who make their living playing bomb and gouge golf. Rory, Jason Day, and Jon Rahm are the biggest examples. They bomb it inaccurately off the tee and then make up for it by scrambling really well from 100 and in. Well you can't do that on this course because the rough is penal and there isn't anywhere to bail out around the greens. You need to be in the fairway and you need to land on the green. Accuracy is more valuable than distance here and Dustin Johnson is killing this course because he is long and accurate. Spieth is generally very accurate, but he didn't adjust well to the conditions from what I saw yesterday. Prime example was on 18 he was sitting right on the edge of a bunker 7 inches from the green on top of some very thick 2 inch deep grass with a downslope all the way to the hole. He tried to use a high lofted wedge (looked like a 54 or 56) of some sort and undercut the ball and it just popped up and landed 1 foot from where he was standing and didn't roll down to the hole. All he had to do was take a 7 or 8 iron and gently tap that ball, the slope would have rolled it down the hill and the higher loft would have left no chance of getting under the ball. Some of the players these days just don't have a lot of creativity. That poor shot made him miss the cut by one.
