The modern game now requires much more from a goalkeeper, 20, 30, 40, 50 years ago Keepers were expected to be proficient in Keeping duties and take goal kicks and punts up to the halfway line with the very occasional role out.
Now Keepers are expected to distribute, act as sweeper and pass the ball out just about every time they get the ball.
Some keepers are good at this some are not.
I think nowadays a good all rounder will always be sought for, good on crosses, good shot stopper and distributor.
