rules are listed by someone else regarding how many players = walkover
secondly, i remember when i used to play BB where we only ever had 6 or 7 guys on our team. It was proper competition but obviously not that high level.
when we had players foul out early, and had to continue with 4 players, we won more often than we lost. and conversleywhen we came up against a team who suddenly only had 4 players, we lost more than we won.
why?
Well, probably be cause we thought it would be easy, but often it was because a box defense really upset the offensive flow. we didnt know how to handle it. and same with the opposition, they would'nt pass it around it looking for the open player, they would just keep driving, so we just had 4 guys block the paint.
plus we put in extra effort when we had 4 players.
so its not that unreasonable. I know its crap, but hey, it used to be crap when we lost to a team of 4 players.
