Spring camp is over and the annual scrimmages are in the books. So, as part of an ongoing series this week, we're taking a look back at what we've learned so far this offseason.

Up next: Maryland Terrapins.

1. The QB competition remains undecided.

Perry Hills reportedly took the majority of first-team reps at practice, but Caleb Rowe and Gage Shaffer were both still involved. Regardless, this competition is far from being over. Head coach D.J. Durkin praised the progress of Hills and Rowe, but he's also not writing off the true freshmen -- Max Bortenschlager and Tyrrell Pigrome -- who are set to enroll this summer.

"They both made great improvements throughout the spring," Durkin said, referring to Hills and Rowe. "We also have two freshmen coming in here in the summer; they're going to have some say in that competition as well."

Durkin can't really be blamed for not naming a starter here. Hills and Rowe combined last season to form the most turnover-prone duo in the nation. They threw a combined 28 interceptions and completed less than half their pass attempts. But, on the plus side, the spring game went relatively well for the signal-callers. Neither tossed an interception. Hills finished 14-of-25 for 102 yards and a score; Rowe was 7-of-16 for 161 yards and two TDs.

2. The new staff is off to a good start -- but there's still a lot of work to be done.

When Randy Edsall was hired in 2011, the transition was a disaster. Despite coming off a winning season, more than 20 players transferred because they didn't want to play for the hard-line Edsall.

This time around? These Terps have already bought in with Durkin and his staff. Defensive end Roman Braglio told reporters this spring he trusted the staff almost immediately. And Durkin seemed to sense that: "We've been very demanding on these guys," he said. "There hasn't been any pushback."

Durkin was pleased with how far the up-tempo, no-huddle offense has come under Walt Bell. But there are still plenty of kinks that need to be fixed. The boom-or-bust nature of the offense led to 14 punts and seven three-and-outs in the spring game. The defense also wasn't helped this spring by the surprise departure of defensive coordinator Scott Shafer but, thanks to the fact both Durkin and Mike London were former coordinators, the impact of the move has been minimal considering the circumstances. New coordinator Andy Buh is also a quality replacement.

3. This could be the beginning of a special offensive line.

Three-year starter Michael Dunn, who has 37 career starts to his name, returns at left tackle. He's obviously a veteran, but this line is really defined by underclassmen and potential.

Former ESPN 300 recruit Damian Prince, now a redshirt sophomore, seems entrenched at right tackle. Center Brendan Moore, also a redshirt sophomore, is the team's most versatile lineman and received a lot of praise for a solid spring. Redshirt freshman Quarvez Boulware and sophomore Sean Christie were among those who saw reps with the first team. And there's even more young talent set to join the team this summer with ESPN 300 offensive guard Terrance Davis and four-star guard Richard Merritt.

There's been a lot of mixing-and-matching on the line this spring -- Durkin said everyone's practiced at least two positions -- and the starting lineup is not set. But it's clear there's literally loads of talent on this line, and we could finally see a glimpse of that this season.
