I was a good athlete and could run. Topped out at a 4.5 40, usually around 4.6 .... had a chance to walk on at a Big Ten University as a Basketball player. In reality I would have never played, I was a D3 type talent. And I’m 5’10”
I married a woman who is 6’1” who was highly recruited as a both a Basketball and Volleyball player by Power 5’s, and who comes from a long line of D1 athletes. Her uncle was a helluva Baseball player too, got drafted by the Pittsburgh Pirates.
The thing is, their whole family can’t run to save their lives. Lots of offensive and defensive lineman. Her Dad was a D1 fullback. Volleyball players, Basketball centers. Her uncle that got drafted was a first baseman. Not much quick twitch in the whole family line.
So now my 17 year old is a 6’2” 195 pound 3B/1B who has the ability to hit but runs a 7.6 60... and is likely headed towards D3. It just is what it is. He’s very happy just to get the possible chance to play College Baseball anywhere...
If I had married a college sprinter, it might have a whole different story! But you know what, when I met my wife I didn’t exactly have in mind what type of athlete we might “breed”!!!
I’m sure people might chime in with “hard work and makeup” are a big part of it, not just genetics, but I’d say that 1) work ethic actually IS part of the genetic makeup, to a large degree and 2) “hard work and makeup” are merely prerequisites. Everybody at the next level has to have that at the next level, outside of the, yes, genetic freaks.
so yeah, I think genetics play a huge part of things. I kept that in mind when my son was undersized at age 11-14. I looked at my wife’s family and thought “there’s no way this kid is going to end up a little guy”. I did hope that he’d develop my speed, not hers!
I tell my son that when he gets to college, skip over the cheerleaders and date a sprinter. He thinks I’m kidding about that!
