There are other "team" sports like wrestling. Track and swimming (minus the relay events), x-country, and gymnastics are some examples. Collective individual's performances earn points for the team. It's a "team" sport, but it isn't.
Having participated in track in HS, I somewhat thought about how my effort would impact the team, but really when the gun went off it was me against the clock. (The clock usually won. lol)
Spencer Lee isn't the first athlete to know the "thrill of victory and the agony of defeat". Just ask Jim McKay and Vinko Bogataj. As sports fans we've all seen that there are good ways, and then better ways, to deal with each.
