The results are far different during his latest swing change.
In the 28 tournaments since Sean Foley first worked with him at the 2010 PGA Championship, Woods has finished in the top 10 only 36 percent of the time (10 tournaments), and he has finished out of the top 25 the same number of times. He has missed three cuts. He won twice.
Then again, Woods went nearly four months without completing a tournament because of leg injuries in 2011. It wasn't until last fall when he could work out and practice without restrictions. Even if the starting point more realistically is the Frys.com Open last October, Woods has five finishes in the top five (and top 10) compared with four finishes out of the top 25.
It's the number of tournaments where he was an also-ran that raises questions.
But so much is different under Foley, unrelated to what he is teaching. Unlike the previous two changes, Woods did not have to cope with physical scars (four surgeries on his left knee) and emotional scars (public ridicule from serial adultery that led to divorce).
He began changing his swing with Harmon when he was 22. He was 28 when he revamped his swing under Haney. Woods is now 36.
It's not as easy, and it shows.
But if or when he goes on another big run, he shouldn't argue if someone calls it a comeback.
