i never understand this idea of 'not ready.'
this isn't boxing. Fighters lose, they aren't, usually, bolstered by gigantic egos. Holm will get in there, and be able to survive a round or two against Rousey and know exactly what its like to be in the cage with the best female 135er. That can't do anything but help.
This same thing gets brought up with Mighty Mouse. Look these guys know what they need to do. And we don't want people who are all hype. someone is going to hit that rousey or MM wall and do everything in the power to climb over it. Others are going to hit the wall and never be the same. We want to see the fighters who will try to overcome and dismiss the fighters that mentally crack. The earlier the better.
