It's no different from any other random Fight Night. It's all about prospects, and in the case of the international Fight Nights, regional talent. In most cases, you have decent prospects, regional champs, and TUF contestants. With O'Connell, I'm not really sure. Best I can come up with is that he was on a win streak. In the case of Grujic and Indich, usually if you are on TUF and you lose your fight in the finale, you are out. They are getting another chance, but since it's against each other, one will surely be out the door. Other than that, it's not really that bad considering it is a Fight Night, and even more so considering it's an international Fight Night.
People pissing and moaning about these cards need to stop and realize what they are. They are Fight Nights. They have always been about prospects and lesser known fighters.
