the fact that they dont fight each other doesn't constitute a tag team. roy jones and dariusz didn't fight, were they a tag team? how about floyd and pac? the brother's do have instances of being a tag team in their careers though, particularly with byrd and sanders.
1. Ive only seen ******s argue the first point. 2. Just because brother A beats a fighter doesnt mean Brother B shouldnt fight them as well, especially if the fight in question is a 50/50 matchup that would sell well in Germany and England.
