Spurrier Logic????? HELP PLEASE!!

Spurrier Logic????? HELP PLEASE!! Can someone please explain this buffoon to me. Against LSU down 9 with 4 min to go and 4th and 15 from the 18 he goes for it. Today down 29 with 7 min left on 4th and 10 from the 15 he kicks the FG. I'm thoroughly confused. Is it me or are these guys really that dumb???
Clearly, I am the idiot as the Tenn coach just kicked a FG with 3:57 left from the 4 yd line down 34. Really??
