It was a relatively quiet offseason in Evanston. There were no additions nor subtractions to the coaching staff (again), there was no quarterback competition, and the union talks were finally put to rest.
In fact, perhaps the most significant offseason storyline unfolded back in late February, when it was announced that Marcus McShepard, along with Steven Reese, would be moving from the defensive side of the ball to wide receiver.
The various offensive advanced statistics for Northwestern in 2015 were ugly. From overall offensive S&P+ (111th out of 128) to Isolated Points per Play (109th) to even success rate—a simple measurement of whether a play was successful or not (see the link for details)—(113), it was a rough year with a freshman quarterback, underwhelming wide receivers and an inconsistent, underachieving offensive line.
