Neither could you have known, so you'd be a fool to say you knew all along that they would go 4-0. That would mean that you're basically claiming to be a fortune teller. Do you really want to go down that road?
You "undefeated" guys really crack me up. It's like you think there's a BYU fairy that's going to leave a signed Taysom jersey under your pillow at night if you predict BYU will go undefeated every year...
Well good luck in getting your jersey I guess.
