This is gonna be a big one. Who do you think will win? I'd have said Kaufman...But Coenen used to fight at over 150lbs, so I don't know...
Coenen won [ame="http://www.youtube.com/watch?v=WcbK66K39lo"]YouTube - Sarah Kaufman vs. Marloes Coenen - Strikeforce: Diaz vs. Noons 2[/ame]
Indeed. People complained about Coenen abusing her size by dropping a weight class, but Kaufman was actually visibly stronger. Coenen won on her grappling skill, not size.
