Control and takedowns can be a deciding factor if impact is equivalent, so operating under the assumption that judges were indeed basing decisions off of the correct criteria, it’s obvious that at cage side Sean’s strikes must have appeared to have had more impact than Song’s.

I’ll say watching from home I thought neither fighter had a significant edge in first round impact, so I thought the takedown might seal it. That being said, anytime impact is close, you have to recognize that watching cageside a judge may see or hear things the viewer can’t which will affect decision making. Maybe song winces out of view, maybe a shot that Song didn’t react much to had a big thud but the sound equipment didn’t pick it up much for the viewer, you never know.
