when it comes to winter sports, i personally dont think its a bad idea...if the kid isn't a benchwarmer on the basketball team. if he/shes playing it usually works out pretty well. just use an example from one of the greats from the girls circuit: danielle jordan.
all-state forward/defender from west ashley's 2002, 2003, and 2005 state championship teams.
she played basketball and usually didn't start practicing with the team until the beginning of march.
and as far as i know..i think her younger sister candace is doing the same thing during her high school career.
although i've seen it work in girls soccer, most spring sports coaches for boys sports often forbid their players of participating in spring sports?
double standard maybe? or who knows...
it doesnt make much sense to me.
