I played basketball, baseball, and football. I never had much downtime. But I think playing multiple sports helped tremendously in my baseball career. I have the agility of all three combined into one.
The one thing I didn't understand was the Minor Leagues, how that part of the business works. I'd see Todd Hollandsworth out there one game, and the next game he wouldn't be there, and I didn't understand.
I play to have fun. I play to win. I play for my teammates.
That is where I got my childhood memories, watching the Home Run Derby as a kid. Maybe some kids are watching me. I would like to return that.
You want to stick with one sport and master one thing and be good, yeah, you might be able to go to more combines, but the life experiences and athleticism you get from playing three sports or whatever will stick with you and help you progress.
I recommend multiple sports for sure. The memories I have bouncing around for each sport, having to juggle some in the same day, it's tough; it's difficult.
