Obviously a swing change is relatively consistent across the board. However, with Tiger, I think his tempo with everything but his driver is considerably better. Could it be better? Yes. But is he also one of the better iron players in the game? For sure.
If you think about challenging that, then consider all the variables Tiger has to deal with on a consistent basis, especially one: lie. Like I said on the last slide, Tiger's never been accurate off the tee, so to expect him to be on the green every time is ludicrous. With the new groove changes, Tiger's challenge has become ever more difficult.
Now, onto the swing above. While many may say that his swing looks upright, if you look at a lot of the best ball strikers in the game (i.e. Sergio Garcia), their swings tend to be more upright. Why?
Because the general consensus is it is easier to control a fade than a draw. With a draw, your release and hand position are a lot more important, because it's the difference between a draw and a hook. With a fade, it's a lot more controlled regardless of the mistake made.
Ask Kenny Perry, however, and he would disagree. He only knows how to hit a draw, and it was in the Ryder Cup I believe where Perry attempted to draw the ball over water where the rest of the players could fade it. Needless to say, Perry didn't get around enough, and the ball landed in the hazard.
I don't have that much negative to say about his iron play, except that he really does need a little better tempo. As for that last 10 seconds of the video, notice how Tiger's club is really "pinching" on the ball. That trapping of the ball is one of the keys to keeping your clubs on a consistent flight, with distance.
