There were spots here and there that he can obviously look back and build on. Through 4 rounds, Woody had 24 holes of birdie or better, whereas Dustin Johnson (finished 6th) had 22 holes of birdie or better (including two eagles).
Wedge play around the greens looked good. Putting wasn't awful. You don't make 24 birdies through 4 rounds without making some putts. Iron play looked reasonably decent. Off the tee? Same deal as always. When he's not dealing with wind - he can manage. When it gets windy - he struggles to keep it in play.
Overall, probably more good than bad. The bad was really bad, but the good was really good, too.
The biggest question is did his back hold up okay, or is he icing it this evening? He showed no signs of being in pain, from what I watched of the tournament anyway. But if he can't get out of his 110% swing aggression off the tee, that pain-free existence will likely only be temporary.
