People simply do not understand the skill level of MLB players. The speed of the game always amazes me. Just watch how easily double plays are turned in the bigs and how easy they make it look. It's crazy.
Seeing a hitter smash a line drive and an infielder have enough quickness to sometimes get in two steps before they dive to stop it is mind blowing to me - especially since I played at a high level.
There are so many things I could point out that most people probably don't even notice.
