Need Help? Non-BCS teams looking for depth this fall

Posted by ESPN.com's Graham Watson
Earlier this morning we looked at teams that had established some depth. Now it's time to look at those teams who are still struggling to fill voids in their game. A lot of times there are more questions than answers that come out of spring, you just have to hope the questions have answers by the fall.

Below is a list of teams that are looking for help in the fall:

Colorado State
It's the same scenario the Rams went through last year, only last year Billy Farris had experience and had shown signs of being a potential starter in the spring. This spring, senior Grant Stucker and transfer Jon Eastman didn't show the ability to start, leaving the door open in the fall.

North Texas
There's really no one part of the defense that can be singled out as all of it has led to the Mean Green's struggles in past seasons. The Mean Green ranked last in total defense (482.58 yards per game) and scoring defense (47.58 points per game). It has two pretty good linebackers in senior Tobe Nwigwe and junior Craig Robertson, but after that the Mean Green need help.

Special teams:
The loss of Louie Sakoda hit the Utes hard last year, and coach Kyle Whittingham said he's settled on Ben Vroman to do the kicking for now, but punting is still up in the air. Sean Sellwood is the punter coming out of spring, but Whittingham is hoping for a strong effort out of incoming freshman Nick Marsh, who could fill the kicking and punting roles.

Running back:
Replacing Dennis Kennedy was the chief concern this spring, but none of the running backs stepped into the starting role. Alex Allen was supposed to be the team's starter this year, but he's still nursing a hip injury he suffered last season.

San Diego State
Running backs:
The running game has hurt the Aztecs for several seasons and even new coach Brady Hoke couldn't get production this spring. SDSU's running back trio of Atiyyah Henderson, Brandon Sullivan and Davon Brown combined to average 2.8 yards in the spring game. He's hoping for help from incoming freshman in the fall, but the running game just might be a work in progress.

Ball State
Offensive line:
The Cardinals' offensive line returned just one full-time starter from last season and the struggles were apparent throughout the spring as quarterbacks were often fleeing for safety during scrimmages.

San Jose State
Running backs:
The Spartans haven't had a solid running game in several seasons, but they're hoping the return of Patrick Perry, who missed the past two seasons with a knee injury, will help. SJSU also is hoping to get contributions from junior college transfer Lamon Muldrow, sophomore Brandon Rutley and senior Chris Reese.

Miami (Ohio)
The linebacking corps has been a strength for Miami for several seasons, but with the top three tacklers gone from last season, the RedHawks are trying to build around Caleb Bostick, who was the fourth-best tackler on the squad.

Louisiana Tech
Wide receivers:
Phillip Livas, who led the team with 607 yards receiving, returns but there is little receiving help beyond him. The Bulldogs are hoping that someone among sophomores Houston Tuminello, R.P. Stuart, and redshirt freshmen Cruz Williams and Richie Casey will emerge to complement Livas.

Rob Calabrese won the job out of camp, but after a rough season last year that produced one of the worst offenses in the country, he might not be the long-term solution. He'll have competition in the fall from Wake Forest transfer Brett Hodges and incoming freshman Nico Flores.
