Putting with the eyes closed is something most of the golfers in the world would find difficult to get thier heads around. The point to the exersice though is to develop a feel between the technique and the distance between you and the hole. Its similair to throwing a ball. Imagine standing about 5 metres away from a mate closing yuor eyes and underhand throwing the ball. I bet with some practice that you would get in their hands more than you would beleive. Its instinct to throw, we have all been doing since were in nappys.
What Rose is trying to do its a bit of this and also trying to gain some trust with the movement. Its a great drill on the putting green. Starting from close and working your way out you'll slowly develop that instinct thats sitting deep within your brain.
Remember putting is 90% chemical and 10% mechanical.
