I thought I knew college football pretty well, but who are these two new Big12 teams playing on NFL Network tonight? One has this ugly bright yellow uniform with a sheep horn or something on it, and the other is in all black with "SF" on the helmet. What does that even mean... "Situational Failure", "Suspect Football" or something like that? And why do they let these two defenseless college teams play on the NFL Network? Please help me out.
