Underestimating pro athletes.

People rightfully make fun of the Pro Bowl, but if you've ever watched the skills competitions you'll quickly realize how otherworldly NFL QBs are. I saw Drew Brees and Aaron Rodgers one time and they could hit a paper clip from 50 yards 10 out of 10 times without breaking a sweat.

Or if you've ever been to an NBA game during warm ups. Good lord. Even the worst dude on the team is just draining them. I went to a Heat game when Shaq was playing for them and he was just ridiculous during warm ups.

Their ability outside of competition is hard to fathom.
