Northwestern's post-spring depth chart is out, and there aren't too many revelations.
Senior Mike Kafka remains the top quarterback and junior Stephen Simmons the top running back. Sophomore Jeravin Matthews and redshirt freshman Alex Daniel are competing for the No. 2 running back spot, though I could see either player claiming the top job at some point.
The only significant change is senior wide receiver Zeke Markshausen moving into a starting job at inside receiver ahead of Charles Brown. Northwestern boasts good depth at superback (tight end/fullback), with Josh Rooks still the starter ahead of both Drake Dunsmore and Brendan Mitchell.
Position battles to watch include right tackle (Kurt Mattes or Desmond Taylor) and defensive tackle (Adam Hahn or Marshall Thomas or Jack DiNardo). The starting linebacker corps appears set, though Northwestern might want to take a look at Matthews as a kickoff return man alongside Simmons and Sherrick McManis.
