I don't know about that, Ninja sort of sucks nowadays, and is a dumb fighter. Sure, Baroni sucks, too, but Baroni can take a better shot and hits very hard. Ninja needs to start using his solid ground game, because his stand-up is bad.
I actually like this replacement. Villasenor is solid.
We all know that Villasenior is a good replacement for the fight. Hence half of the replies. True Ninjas standup isn't so swell. Nor is Baroni's takedown defense. Baroni's ground game is shameful. And I wouldn't see Ninja standing for too long in a striking game. He would've exposed baronis weakside. Say what you will Damone, but you can't convince me on Phil Baroni defeating Ninja.
