The world hasn't seen a successful professional dual-sport athlete since the days of Bo Jackson and Deion Sanders.
But, the trend of the multi-sport athlete's fade into obscurity goes past professional and college athletics, Leavenworth High School baseball coach Joe Allison said.
For Allison's baseball team, he said of his 10 top players, only two are dual-sport athletes.
Allison said the emphasis placed on offseason showcase baseball gives his players the idea that the only way to maximize their baseball potential is to focus on one sport.
"A lot of my kids, basically, their understanding is in order to be successful as a varsity athlete in baseball, they feel like they need to play all year-round," Allison said. "Every time I come across a kid that's one of the better baseball kids, they're typically your two- or three-sport athletes."
Athletic specialization in high school isn't just a baseball trend, however.
Leavenworth track and field senior thrower Willie Morrison, a three-time state champion, decided to quit playing football his junior season to focus on throwing.
While part of his decision came from the fact that he didn't like the running, he said he decided to focus on throwing once he found where his talents lie.
"I found out that I'm actually good at track," Morrison said. "Other sports, I mean, I played. But, track is what I was made for."
Morrison saw success in his specialization, but Allison said in his experience as a varsity coach, playing other sports is generally nothing but helpful for his players.
He said the reason for this stems from the athletic ability that other sports can build in athletes along with the opportunity to continually participate in a competitive sports atmosphere.
"The most important thing is the competitive nature in things," Allison said.
"There's just different aspects to all these different sports that would make you successful when you combine them together, that makes you a much better overall athlete."
Morrison also said he looks at the decision to specialize from a physical standpoint.
More specifically, as a track and field athlete, Morrison said his track and field specialization greatly reduced his chance of injury and increased his chances of succeeding as a thrower.
"The only injuries that will happen are the ones that you'll bring on yourself," Morrison said. "There's no contact, it's not like someone's going to jump on you and break your leg. You won't hurt anyone else besides yourself."
But, for younger athletes, Morrison said he would recommend they play as many sports as they can to discover which best utilizes their talents.
Once an athlete discovers where he or she would succeed, Morrison said that's when an athlete should seriously consider specializing.
"If you specialize in a sport, you will become better at that sport," Morrison said.
"You could be good at two sports, but then once you play just one, you will be great at that one sport."
