I am looking at them as overall players but the main focus is bowling. What makes you think Giles is a better bowler SJS? It suprised me that you think Giles is better
If you look at Giles bowling post Nasser Hussain, you find a huge change. Earlier, with his over the wicket, outside the leg-stump (for right handers) attack was not just very negative, it was not allowing his natural flight to show and the turn was of no use and seemed sesign to contain anyway. But now, bowling round the wicket, mostly, with a classical left armers line around off stump, moving away he is forcing batsmen to try and drive him to the off side, tempting them to do so and this is what good left arm spin bowling is all about in test matches.
Vettori's problem, according to me, is his grip. If you have noticed, he holds the ball between his thumb, index finger and middle finger, that is, a thumb and two fingers. Normally finger spinners would grip with the thumb and three fingers. The thumb and the ring finger on the underside of the ball. This gives a much stronger grip and allows the strongest two fingers, index and middle finger to really tweak the ball.
Vettori' s grip has the thumb and middle finger on the underside of the ball, leaving the lone index finger to do all the work. This makes his tweak very weak and he just rolls the ball out of his hand.
Moreover, due to the weak grip he is unable to push the ball horizontally forward at the time of delivery which makes the ball go as far as possible, parallel to the ground before the sudden dip which provides the great finger spinners with the sudden dip that causes the batsmen to misjudge the length. Vettori is unable to do so. Thus he just throws the ball up in the air and it moves in a regular arc. He does manage to pitch on length but the trajectory is not deceptive if you get what I mean.
I am absolutely astonished that no one has corrected his grip in all these years. I have not seen any major bowler in the world bowl with this grip.
Besides trajectory his lack of biting spin and sudden bounce/kick off the wicket is also the result of this timid action.
