Thinking in sport has shifted from the idea that time is best spent working on your weaknesses to time is best spent developing your strengths. Of course it would be great for Mutch to become elite with both feet, but it's certainly more achievable for him to become elite on one side if efforts are focused on that particular goal.
Yes and No, it is the ability to kick with both feet that helped make Sam Mitchell into the player he is.
It is a mighty good skill to have and one most players, would love to have.
Well he can kick with both feet. Nobody is suggesting anything other than that is a good thing. But if he is to become an excellent kick, it's more likely that he will achieve that goal if he focuses his efforts on one side. In most occasions players have the opportunity to turn onto their preferred side. It also makes the more predictable to their teammates.
You can be an excellent kick on both feet - A few examples - Mitchell, Hawkins, G.Williams and D.Jarman..
And also Peter Matera from the Eagles, particularly on the run.
Check out each of his five goals in the '92 GF or that time he scored 7 against us in a night match at the 'G in the late nineties ('98?), but that was primarily in an unaccustomed role at full forward for him.
Matera was phenomenal on either side.
