I like a lot of what Chito does, but he has a problem: he has rather slow hands for the weight class and because of this, is wary of attempting counters.
It's actually very smart of him to acknowledge this weakness and avoid rolling the dice in exchanges. Problem is, an opponent with the right skillset can use this to control/shut down his offense. Sandhagen and his team had obviously dialed in on this tendency. Later in the fight, I heard Cory's cornerman bring it up, calling on him to 'overload' Chito with activity.
I knew that Sandhagen would outpoint Vera with ease because he has the perfect skillset to do so: he is mobile, rangy, quick, uses a good variety of attacks and is constantly feinting. He also did a great job shutting down the one technique that Vera relies on even as he is reluctant to exchange: his low kick. Sandhagen mostly neutralised it by continuously switching stances and moving in, out, laterally.
As I said, I like Vera as a fighter and was happy to see him climb the ranks. However, I feel that this is the end of the line for him, as far as title aspirations. There are too many ways to beat him and the top guys all have what it takes to do it. As much as I hate O'Malley, he should be the favorite in the rematch as well, and that will probably be the go-to fight for Dana once O'Malley loses and the UFC is looking to rehabilitate his status as a contender.
