It also can't be discounted that Chryst was seriously injured at the end of last year. It was not even clear that he would be ready to play at the start of 2017. Even if you look at "same time, last year", it was clear that Stanford's passing game was very pedestrian, at best. Costello, OTOH, has shown the ability to make the tough throws against good teams. That is a much different situation than last year. What happens going forward is understandably less clear. The sample size is small enough that we don't know what Costello's "mean value" is, or will become, as he matures in the system. Right now, it is safe to say he hasn't disqualified himself as a "solid" stating QB for Stanford. He may well be more.
