I bet not. Some families start teaching fundamentals by playing out in the yard at a young age and even by t-ball, those kids have a good grasp on the game. Most t-ballers have never even worn a glove by the time they sign up, so you have one or two kids who take the game seriously on a field with a bunch of other kids that have no idea how to play.

It doesn't mean the dad is an asshole, it just means these kids love the game, are good at it, and will advance nicely through LL into HS and even college ball. These are also the kids that become major leaguers.

Our son was like that. We played ball in the yard...not because we were forcing him to be a ball player, but because my husband and I both love the game so it was only natural that we taught it to him from an early age. He was the kid that could field grounders, shag pop flies and hit a ball from the pitch instead of from the tee.

Yes, he sometimes got frustrated when his teammates were playing in the dirt or staring off into space instead of playing the game, but overall he always had a good attitude and good sportsmanship about it.

TL;DR: Just because a kid is good at a sport does not make his dad an asshole.
