Me too. Burnout is the obvious one but I think you can also learn techniques from other sports that will help you improve. You can take basic principles in one sport and apply them to another. Playing football growing up taught me about getting low and using leverage, which helped me in 1-on-1 battles. Baseball helped me with hand-eye coordination as well as using my hip/trunk area better. As much as I love watching soccer, I am a terrible player. However, I am a somewhat competent defender because I took principles that I learned playing basketball such as footwork, angles, and taking away the opponent’s strong side and applied them to soccer. With some tweaking, I’m not all that bad.
I think the most important thing is that kids be kids and let them try their hand at a bunch of things. Maybe they’ll gravitate to, and be good at, something that you didn’t even think of. If they don’t make it to the big time (they most likely won’t) at least they got to experience different things and have fun doing what they wanted to do. I’m grateful to my father for not pushing anything on me. Like a typical European, he wanted me to play soccer growing up. Most kids play catch with their fathers. I played soccer. Eventually, he saw that it wasn’t my thing so he did what made me happy. He pitched and fetched countless baseballs. As for hockey, let me tell you, it’s pretty hilarious watching a 40-something Serbian immigrant strap on road hockey pads and eye down a bunch of slap shots.
