It all boils down to a matter of class. Does the Bronze level rider move up or stay at that level once capable of moving on? Does the coach of the winning team put in second and third string players to lessen the devastation on the other team? Whether the rider and/or coach has class will determine which it will be.
I was on a track team in high school that was entering it's 4th unbeaten year my first year on the team, they continued to go on unbeaten for another TEN or so years. With the exception of the teams with which we had intense rivalries, the coach would substitute the JV runners once we were clearly going to win.
He taught his teams good sportsmanship, something even more important than winning.
