I saw many cases of burn-out. Also parents pushing one sport on their kid when the kid preferred another.
Lot of parents use "My kid plays for a travel team" as a status symbol.
I wouldn't say attitudes like that are rampant in my area but it's far from rare. Most kids sill play multiple sports and make their decision to one sport when they move on to college. As far as college.... few make it in college. - JamesJM
