How do I know this? Simple.
He's a yawner. Literally. He yawns during games.
I have seen parts of only two Braves games this season, and in both games, he was caught on camera yawning. This is a guy in his early 20's, batting .150 in his first extended big league action, and it seems like he doesn't have a care in the world.
Great players take pride in performing. At the very least, they pretend to care.
Maybe I am overreacting, but Freeman isn't one of those guys.
