This is my favorite clip from Moneyball. "I'm just sayin', his girlfriend is a 6. At best"
I don't know if it's a realistic portrayal of baseball scouts, but I think there's some truth to it.
There is definitely correlation between elite athleticism and big dick energy, but I'm not sure scouts get the causation right. They assume that cocky kids become good athletes because they're cocky, but I believe some good athletes become cocky because they're good athletes.
