Bill Russell, 1969 Celtics.
The entire team was completely worn out. Over the previous decade they'd played an additional season and a half relative to a bad team in playoff games alone. Lousy shoes, rattly floors, useless surgery, bad food - a 35 year old basketball player in 1969 pictured next to a 35 year old basketball player today looks like a father and son photo.
The coach also had to be the starting center. Surely they were just tanking for a high draft pick? That didn't work in the regular season, as they made the playoffs.
And then they stranded ten thousand balloons in the rafters in Game 7 of the finals.
San Diego should also have a G league team. I'd buy a season ticket.
