Speculation is in order, so we can't really be wrong or right. :-) In the computer game the bikers have "learned" to roll over all the skaters early, ignoring the catchers (and the ball) altogether. After a game the score is usually enormously lopsided for one side - that side left protecting its last remaining skater!

We're not talking usual circumstances here - there's probably a good counterattack on the bikes unconsidered - but in that rare instance does anything prohibit a catcher from removing the glove and acting as skater/scorer?

I accept it as uncontroversial that a biker cannot score (or even handle the ball). But I suppose a biker could dismount in the dugout and take to the little wheels. In theory then the game could be played even down to mano a mano.
