I am glad I read this post. I have never talked about this rule with anyone but I was definately reading the rule different than the rest of you. In my head I was reading that the captain could request a matchup, which to me meant they could bring in subs to match up the incoming players. The example I could think of was if team A brought in thier three biggest players who had been sitting out and team B was also giving their big guys a break. This way, team B wouldn't be at a serious disadvantage until the next dead ball which could be minutes. Am I crazy for thinking that?
