This fight needs to happen!!!! This would be a great fight when one looks at marketability and skill!!! Next K-1 or Pride, they need to give the people what they want.
Prolly won't happen for another year. BJ is still at Welter, and Sudo will prolly fight more in UFC.
But no doubt, it would be a fight for best P4P fighter in the world.
I don't know if Sudo is best PfP. But he is in the top ten in his weight division, and very skilled. Plus, marketability, it would be priceless.
