Parents Role Is To Help Their Kids See The Bigger Picture
R.C. Buford is a PCA National Advisory Board Member and is the President of sports franchises for Spurs Sports and Entertainment. In this current position, Buford serves as the GM of the Spurs (@spurs) while overseeing the sports administration for the other three teams in the SS&E family (Austin Spurs, Silver Stars and San Antonio Rampage). In the summer of 1997 he became the Spurs Director of Scouting, was promoted to Vice President/Assistant GM in the summer of 1999, and became the Spurs GM in 2002. In Buford's time with the Spurs, the team has won five NBA championships.
Buford suggests in this video that parents want to be supportive of their child in any sport they're playing. Diversification between sports allows children to grow even more so as a teammate, player, and person, as Buford points out, and the more opportunities a parent gives their child the better.
