I will never sacrifice individual success for "points," but if someone is a miler and can score in the 2 mile I see no harm. As for the relay, every athlete I have ever coached puts team and relays over their own accomplishments. It's me who talks them out of the extra event. Why? Because winning the individual title feels good, winning as a team and jumping in each others arms in pure elation is so much better.
I had a girl who won regionals but our team did not have a good day and she failed to qualify and she was in tears. She would trade that victory to make it as a team any day. Anyone who says otherwise has never. Even on a winning team.
Track has a different feel than xc but can be just as exciting when you are up against a rival or going for a historic win. I'll say it again, Nothing beats a team win!
