I think Frank's shown he has better stand-up (even though Ken improved from when he started, his striking isn't nearly as proven) in the Baroni fight. Beating a boxer on his own turf because you can't shoot with a bad knee is pretty damn impressive. Even if Ken does manage to get the fight to the ground (which I've yet to see him use striking to get the fight where he needs it to be... on the ground) I think Frank is more agile on the ground. I wonder what weight class this fight will be at.
Thanks to NikosCC for the sick sig!
