Relegated North American Professional Sports Teams Since 2000
In this alternate reality, the NBA, NHL, MLB & NFL decided in 2000 to follow the model of football leagues worldwide and relegate their worst performing team each year. Therefore, name the team in each league with the lowest winning percentage by year (i.e. those that were relegated).
If multiple teams had the same "winning" percentage, the team with the worst point/goal/run differential was relegated.
Several of these teams were so embarrassed by their relegation that they changed names/cities.
