He scored a TD and some field goals. Look up all of his games against defenses that had a pulse. You won't find many (maybe none, but it's been a while since I last looked this up) where he led us to more than a single TD and then some field goals. It's quite amazing that he was consistently only good for a single TD against decent or better defenses, even after he left BYU.
There's no easy answer to being a coach. Because we know the outcome it's easy to say we should have kept driving. After all, we know we lost because we didn't. But what if Anae had kept the ball in Heaps hands and Utah, known for making plays on defense, scores an interception on the very next play, or forces a sack/fumble? Then we'd all be complaining a full decade later how stupid Anae was to put do much pressure on the shoulders of a freshman on the road in a hostile environment, and that he should have settled for the FG.
