Disabled sports are thought-provoking because the rules always seem to take mechanics into account. How do you adapt a sport so disabled people can take part and how do you rate their ability against other disabled athletes? (And why does that cheerleader’s accent swap between English and American?)
Wheelchair rugby is particularly interesting. Player ability is rated on a point scale: the less disabled a player, the higher their point rating. A team can only have players worth eight points total.
There are seven classes ranging from 0.5 to 3.5 with functional characteristics identified for each athlete class. In general, the 0.5 class includes those athletes with the most disability and the 3.5 class includes those athletes with the least disability or “minimal” disability eligible for the sport of wheelchair rugby.
In international wheelchair rugby the total number of points allowed on court at any time is 8.0. That is, the total points of all four athletes actually playing cannot exceed 8.0 points. A team may play with a lineup that totals less than 8.0 points, but not more.
Must add a wrinkle to team selection; more players with less mobility or fewer with more?
I believe a similar points system is used in Warhammer 40K.
