I can't imagine Cal going to the Rose Bowl with three losses under any scenario. They'll be lucky to hang onto a top 25 ranking this week, and they're not going to impress anyone if they beat Stanford in their final game.
It is doubtful Cal will make it, but it'll take some serious voodoo for LSU to end up in Pasadena. Like I said though, LSU-Michigan would be one helluva game.
