Good putters, good place kickers, and good FT shooters have the ability to get in a "zone." They are a be to block out everything and put their focus only on the hole, uprights or goal. They don't hear crowd noise or anything else. There's some interesting research out of California where people who never shot with a bow and arrow before were taught through feedback to get in the "zone." Within a matter of a few days or less, they were shooting at least competitively. The secret is not just practice but learning when you are in that concentration zone and how to get there.
