I dunno, it makes a lot of sense to me. I think everyone is aware that Fitch has been the #2 fighter at 170 for the past 6 years or so. Everyone is also aware that he will NEVER beat Georges St. Pierre in his lifetime, so this makes him the clog in the world's biggest logjam in MMA. He has steadly been beating prospect fighters and knocking off contenders for years in a way that is frankly uninteresting and isn't the fight that fans are looking for.
In times like these I have to remind myself that this is entertainment AND sport. The UFC does not have logical rankings because dollar values mean more than the significance of earning a rank.
Volkmann is another guy I don't mind seeing go along with Russo. They're the same breed of fighter that Fitch is but they're just not nearly as good in their respective divisions.
Valddy will probably hang the gloves up, it's sad but it's right thing at this point. The Janitor has had a good career.
Che Mills I think could have gotten another chance along with Sass. I think we'll see them back in the UFC in a year or so. Etim I'm not so sure of. He was posterized by Edson Barbosa with one of the most brutal knockouts imaginable. He'll be spending a long time trying to shake that memory from the fan's minds.
Jorge Santiago and Jay Hieron are journeymen who were brought in for one reason, to lose to guys the UFC were trying to promote. They're both knockouts waiting to happen. They'll probably get another shot down the line but again only to lose to UFC prospects.
The rest of the guys I don't know about or am uninterested in. I'm just looking at it objectively. It's all about the money and these guys probably don't bring enough in to warrant keeping around. Business is business.
