Then, there is the offensive line, where concern is a better way to describe things.
No matter what happens in training camp, and the first few games of the season, judgment on how the unit performs will be held until deep into the season after quarterback Tom Savage was battered last season and running lanes were opened with inconsistency.
One of the most important cogs on the line is 6-foot-6, 290-pound Desmond Wynn, who is No. 19 on ScarletReport.com's Top 25 countdown of most important players for the 2010 season.
Wynn, a red-shirt junior, holds three career starts, and missed the St. Petersburg Bowl and spring practice because of shoulder surgery. He could have used the practice time to build continuity with the rest of his unit, and also to get reps because of his inexperience.
Wynn is penciled in as the starter at right tackle, but injuries or performance by himself or others could force to be shifted to left tackle or right guard, a position he made three starts early in the 2009 season before giving way to Howard Barbieri.
Shoulder injuries have been an issue for Wynn since he arrived at Rutgers from St. Mark's High (Bear, Del.) as a defensive lineman but was converted to the offensive line. He did not play in 2007 and 2008, but set up for 2009 by winning the Mark Mills Second Effort Award as the most improved offensive player that spring.
As Rutgers tried to settle its offensive line early last season, Wynn saw plenty of playing time, including the trio of starts, and gained valuable experience.
Wynn has a long reach and good footwork, which will help him on the edge as the Scarlet Knights looks to replace Kevin Haslam, but is one of the unknown performers entering next month's training camp.
