Let’s remember the best kicker in the NFL for both accuracy and distance was an UDFA. It’s hard to know who will be a good NFL kicker until they start kicking in the NFL.
The problem with kickers is that their competitive personality is very late forming.
Football in general is a late forming sport. You don't know who you are really going to be until you grow into your body.
Soccer on the other hand is a very early forming sport. That's why the major sports leagues have identification camps at 9-11 years old. Most of the world's best players were already known for a decade before hitting the bright lights of the World Cup.
So what is it that humans form the very latest in their development? We gain our best bodies somewhere in our mid-20's if we aren't a bunch of lazy slobs as teenagers and young men.
But we form our brains under pressure later in life from repeated stressors. We learn how to deal with conditions by actually being in the condition itself.
This is why it is a crap shoot trying to find the next Justin Tucker. You are taking young kids who have literally experienced nothing of serious stress, and trying to figure out if they have the mental fortitude to rise to the moment 3-4 times a game.
Being an NFL kicker is an extremely late forming talent. That is why there are so many failures. You have a higher likelihood of being a successful lineman, running back or line backer.
The worst position in the league is the placekicker because you are more likely to fail more than succeed because the minimum bar of success is so high in the league now.
Just as a point of fact does anyone here know the FG% of the great and immortal Lou Groza? This fact alone will tell you how expectations in the league (coaches and owners) and fans have changed.
