Forgive me if this has been discussed regarding tiger...I'm fairly new here.
This has been discussed by the various announcers...Miller made a few comments on it during the NBC coverage in the past few weeks...and I'm sure Kostis has and will discuss it over the next few weeks.
IIRC, (and I'm by no means a guru, so what I'm saying is subject to my aging memory) the root cause is that his hips turn too fast...and his arms lag behind (how I would LOVE to have hips that could turn in tandem with a 130mph swing)...when his arms lag behind, he has to drop down to bring the clubhead onto the ball. The clubhead's face, after the drop is open...and 9 times out of 10, it results in a missed shot to the right. This is what Tiger and the various TV analysis refer to as a 'block'.
Like all of us, when we are fearful of a particular fault, we tend to overcompensate in the other direction...in this case, Tiger pulls it, like he did on #2 on sunday.
Personally, I think that Tiger's recent swing change with haney isn't the magic bullet he keeps saying it will be. There was nothing more perfect than Tiger, after his initial swing change with Butch. That swing resulted in that amazing stretch in 2000-2002, where Tiger was simply flawless. Part of me thinks that Haney almost brought in this new change just for changes sake, you know, justify his salary....I dunno, if I were Tiger's new coach following Butch, I think I would have just continued Butch's work.
There's no need to come out of your shoes like Tiger does to put the Ball in the center of the fairway a long way out. If Ernie can do it with a fraction of the effort....Tiger can dial back his swing a little bit and get some consistency.
Even though Tiger is on top of the rankings now, I think his Driving problem will eventually be his downfall. 2 reasons I feel this way....#1, eventually someone will develop similar 'scrambling' ability...but with straighter driving....#2, I can't help but think that now that Tiger has inherited the Seve comparisons (with respect to scrambling) he might inherit Seve's fate....
I dunno, I love Tiger...I really do, but I'm getting sick and tired of pulling for him each Major and watching him dunk the ball in the right trees.
