Dont remember exactly, but they were something like 4 yards on first down, 4 yards on second down, and conversions on third and (nonpunting) fourth downs. My suspicion is by that metric, we had a (much?) lower than usual share of successful plays: e.g. three and out, three and out, a first down, then Love busting out for six. How many successful plays in those series? Maybe 2, 3 of around 11. Thats what it looked like to me this season.
Bill Connelly has a successful plays metric. Here's how he defines it:
50% of needed yardage on first down
70% on second
100% on third and fourth
By this standard, over the course of the entire year, Stanford had was not terribly efficient: 39.9% of plays were successful, 89th in the country. Stanford made up for that with outstanding explosiveness (#8 by Connelly's reckoning), though of course you'd like to be explosive *and* efficient.
Still, as I think various data shows, the offense really did perform better in games Costello started or played the majority in. So I suspect many more plays were "successful" then. (I calculated that Costello's successful plays rate on pass plays was 45% against ASU and UCLA, IIRC. That was a good bit above the season-long average of 40.7%, which was 65th in the country.)
