Whitehead is a great fighter out of Miletich camp. He was on TUF2.
Brink is a former UFC veteran and porn star. He's got some skills, but is mainly one of those guys with a name from the old days who are stepping stones for guys fighting today.
I guess the one dude is a Lister prodigy like you said. Kyle's name looks familiar to me on paper. According to Sherdog fight finder he's a submission guy. He's fought veterans such as Drew Fickett, Ronald Jhun, Shannon Ritch, Thomas Denny, and others. He's piled up an 11-7 pro MMA record, with ALL 11 wins by submission. So if the weird name guy is a Lister trained dude it should be a good submission battle.
