Our local paper ran a story recently about the athlete/musicians. Football, hockey, swimming, choir, orchestra, band, everything. My son did x-country and band. The hierarchy is competitions and performances take precedence over practice and rehearsal. Conflicts are dealt with as they come up.
For parents and kids, there is a fair share of driving fast and an occasional meal on the car. But the sport season is usually only a could of months. Unless the kid goes on to another one next season.
The worst conflict was my son wanted to do track and the spring musical, but everything conflicted so he did have to choose. Some kids do one one year, and the other the next year.
