One more half to go.
The game started sluggishly for both teams and got worse after Jordan Canzeri suffered a lower leg injury. And then: Akrum Wadley! The forgotten man in Iowa's running back rotation -- he was fourth-string at one point -- came off the bench to rush for a pair of second quarter touchdowns, including a very pretty 34-yard run around the edge where he walked into the end zone untouched.
At that point Iowa had a 16-0 lead and things looked good. The game turned on two plays. On one, Northwestern converted a third and long situation with a deep pass; a few plays later they had a touchdown and Iowa's lead had been cut to 16-7.
