And at i9 Sports, sportsmanship is valued so highly there are weekly rewards for it.USAToday_May2013

The recreational youth league, which has programs in 280 communities in 28 states, designates a specific value of sportsmanship — being a good buddy, humility, leadership — for coaches to emphasize each week. At the end of the week, the player on each team who best exemplified that value gets recognized.

Parents also have to pledge to display good sportsmanship, and not use negative or derogatory language with officials, coaches, other parents or kids. They also pledge to keep fun as the main emphasis of the league.
“We believe there’s great value in competition, healthy competition,” said Frank Fiume, founder and CEO of i9 Sports. “But learning how to win with grace and lose with dignity is key.”
