Follow through in putting

This is what Jack Nicklaus said about follow through. And if he said it, then it must be true, right?

The follow through, necessary for tee and fairway shots is no less important on the green.

It is especially important on short putts, the follow through coming more naturally on long putts. It can also cure a lot of backswing mistakes.

I perform my follow through by drawing an imaginary line along the path the ball will take, then concentrating on carrying the putter face along this line for at least 5 inches after the ball is struck.

Following through helps to assure a solid on-line putt, regardless of the backswing, and lessens the tendency to quit on the short ones.
