Stanford's scoring average surged from 23.8 points per conference game in 2014 to 40.9 in 2015, a 17.1-point increase that pushed the offense's rank from 11th in the Pac-12 to the very top spot.
Christian McCaffrey and Kevin Hogan earned the headlines behind this massive jump in productivity. And that's understandable: The former is the new NCAA's new single-season record-holder in all-purpose yardage, and the latter ranks among the top five nationally in both quarterback rating and yards per attempt.
But there's another component of Stanford's attack that's made a colossal surge in 2015, and it shouldn't be disregarded: After a yearlong hiatus, the Cardinal's offensive line is again the unit's beating heart.
