Athletic talent tends to filter up.  The best athletes in middle school get invited to play for the best traveling teams.  The best athletes from those teams get selected to play at the best private high schools.  The best athletes from those schools get signed to play at the best colleges.  But then the system breaks down.  The best athletes in college get drafted by the worst professional teams because of the lottery system. 

Something I've been noticing for a while now is that good athletes don't know how to lose.  You'll have an athlete who's won state championships in high school and national championships in college, but then lose their first several or dozen games with their professional team.  They literally haven't lost since they were children.  As much as it's a good thing to select for talent and success, I feel like it sometimes hurts the process when a person never experiences losing. #sports
