I think it is not so much the kids don't want to be 3 sport players, but do not have opportunity--especially at the larger schools which all the article quotes come from. Basketball teams have small rosters, soccer teams give preference to club players, and baseball and football coaches try to bring players up through other programs, so there is rarely room on a roster for the player who decides he or she would like to just try another sport unless he or she is the rare super athlete (Bo Jackson, Deion Sanders type). A more accurate picture would be to see how many athletes try out for multiple sports only to be cut somewhere on the way forcing him or her to focus on one sport.
