"I think one of the big differences that's very rarely articulated is the fact that while Tiger in his dominance always - for whatever reason - was in this quest to get better, I don't remember Jack ever saying that," Azinger said.
"Jack might have made some tweaks and twerks here and there ... but Tiger has made astronomical changes in a quest to get better. And as a result, Tiger has actually got a little bit worse. I think we can all pretty much see that."
Azinger said several golfers have made a mistake changing the swing, but that Nicklaus was not one of them.
"Jack understood that if he could stay the same, he would still dominate," he said. "Tiger didn't need to get better. He just didn't need to get worse. He needed to stay the same and he could still dominate, and in his quest to get better, it's kind of backfired on him."

Butch Harmon years (1996 - 2003): 39 wins, 8 Majors
Hank Haney Years (2004 - 2009): 31 wins, 6 Majors
Sean Foley (2010 - Current): 8 Wins, No Majors
Clearly the first swing change didn't hurt Tiger, he nearly matched his total wins and majors, in a shorter period of time. Right now, he's working with Foley, but clearly has been injured, which I don't think Azinger takes into account. If his original swing caused him to have that knee injury than a swing change would be needed to help extend his golfing career.
I am not a big Tiger fan, but I will defend him on this one. I don't think Azinger sees the small details about this. Yea, the swing change didn't really hurt Tiger when he went from Butch to Haney. It is hard to judge his move from Haney to Foley because he's been injured. Clearly Tiger's game suffers when he can't practice a lot. I would like to see Tiger being near 100% healthy over the next 5 years to see how his career pans out before they start making comments about his swing changes.
