It happened to our high school team once in this instance. I think what happened was, and this is a possible issue when you rotate captains as we do- but when you win the toss you can defer choice to second half, kick, receive, or defend a goal. What happened to us was there was a miscomm, between coach/captain and captain/official between defer and defend a goal. if the opening toss today was ruled a defend a goal instead of defer, then Missour got the choice for the second half. Otherwise ???
