1. Establish an identity on offense: An injury-plagued unit never got on track last season, finishing 10th in the Big Ten in scoring (26.2 points per game). The playbook definitely shrunk without standout running back Venric Mark, who is expected to receive a fifth season of eligibility and return this fall. Mark adds to an already strong stable of backs, but the team's most experienced quarterback, Trevor Siemian, undoubtedly is a pocket passer. Does Northwestern continue with a two-quarterback system (Siemian and Zack Oliver or Matt Alviti) or stick with one guy? Does it return to the pass-first scheme that proved effective in 2008 and 2009 or the run-pass mix that worked in 2012? These questions and others must be answered in the coming months.
2. Solidify the offensive line: After several years of progress, the group took a step back last season, allowing 36 sacks, the second-highest total in the Big Ten. Northwestern must establish chemistry earlier and build some depth before fall camp rolls around. The potential good news is everyone returns, including veteran center Brandon Vitabile. There should be plenty of competition throughout the offseason to fill the other four spots and build some depth the Wildcats lacked in 2013. If Siemian is the starter, he'll need better protection, as he lacks the mobility of recent Wildcats signal-callers like Kain Colter and Dan Persa.
3. Bolster the defensive tackle spot: Defense really could be Northwestern's strength in 2013, as the Wildcats should have their deepest group in the secondary in recent memory, as well as Chi Chi Ariguzo and Collin Ellis at linebacker. Three speed rushers return at defensive end, but the tackle spot is a bit cloudy after opponents averaged 167.7 yards rushing per game against Northwestern last fall. It will be important to keep Sean McEvilly healthy and find others around him like Chance Carter, Greg Kuhar and C.J. Robbins. Coach Pat Fitzgerald talked about getting stronger up front after a disappointing 2013 season, and the defensive tackle group certainly must respond.
