I certainly agree that photos and video can mislead. Always best to get out and see the top players in person to really get a feel for what they are doing.
As for now vs 2000 - 2000 - because that motion was IMO more on 'auto', vs now where Tiger is fighting his tempo as a 'swinger' and his clubface control is in his right hand thanks to a left hand grip that doesn't match the motion he is trying to make.
That said, his current motion is 'almost' better than 2000, and could be with a few minor adjustments. Much better plane now, but his left hand grip is the reason he is fighting the new swing, and his tempo/balance issues have less margin for error now than in 2000, when he was more of a hitter.
There is a different left hand grip for swingers vs. hitters? What is Tiger's current left hand grip and what should it be?
