I don't think most other fans know about them. I read the arkansas forum this morning just to see how their transition from "we got this" to "crap!" happened. In the course of the game there was plenty of, "who are these guys? Where did they come from? We thought we were gonna win the down low game but damn.".. and more like this.
I think all but the 5% of actual hard-core CBB fans really had any idea who we were.
