When I was in Junior High School, everyone feared the campus bully whole talked a big game. But when someone finally stepped to him and started swinging, he couldn't find a desk big enough to hide under, as you could tell he'd never really been punched in the face.
That's kind of what Bryan Caraway thinks of Aljamain Serling -- minus the bully part.
As Caraway recently told MMA Junkie, Sterling talks quite a bit to pump himself up a bit and hid his insecurities. Furthermore, while Aljamain is a talented athlete, you can see he's not to fond of getting punched in the face.
