Here is an idea about “competition” that I have tried to sell unsuccessfully to a number of coaches about young ladies learning the sport of fastpitch softball.
It is, yes, compete, but primarily, almost entirely, compete against yourself only – no one else on either side of the field. What is important is not the final score, but are you getting better, were you better this game than the last game, are you improving even if just in small steps.
If we win 8-0 with sloppy play; that's not winning to me. If we lose 8-0 against a far superior team that should have scored 8 runs per inning against us, well, in my mind we won big that day. That goes for the team – but mostly it should be drilled drilled down to the accountability of each individual player as an athlete and teammate.
Did you do honestly do your best today? -- which includes preparation, learning from past mistakes, building on strengths, and attention to the game. If the answer is “yes”, we have a young woman that won that day.
