I remember it as you posted that he said kicking on their non dominate side, ie he kicks better on his left foot than 90% of the natural right footers in the team rather than 90% of the whole group. IIRC there was a discussion on how many players wont kick with their left and do dickie checkies and stuff up.
This is so true. It amazes me that players can be picked high up in the draft, but be completely unable to competently dispose of the ball on their non dominant side.
It has been proven in most sports that athletes struggle more when playing against left-handers, or those who are ambidextrous. Be it tennis, football, soccer etc.
It is so much easier to corral a player who can only dispose of the ball on one side. Players study their opponents closely, and they know who can dispose of the ball on both sides and who cannot.
Similarly it annoys me that our kicking accuracy does not appear to have improved significantly since 2013.
Kicking skills, and and the ability to dispose of the ball on the non-dominant side, should be something that significant time is spent on in football. Unfortunately, that certainly doesn't seem to be the case.
