With training camp nearly two months away, there’s plenty of intriguing position battles to keep an eye on. However, there’s not one position with more intrigue heading into the summer than running back.

The NFL has turned into a ‘pass happy’ league, which has tremendously devalued the running back. A lot of teams are going with the running back by committee philosophy. Having said that, when things get tight in crunch time, coaches must decide who gets the ball in those pivotal moments.

Here’s a look at the top running back battles heading into training camp:

St. Louis Rams – With the 10th overall pick, St. Louis created shock waves throughout the football world after selecting Todd Gurley. The pick was bizarre for multiple of reasons.

First of all, before Gurley, there hasn’t been a running back taken in the first round since 2012, when Trent Richardson went third overall to the Cleveland Browns.

Last year, the Rams selected Tre Mason in the third round. During Mason’s rookie campaign, he rushed for 765 yards on 179 carries with five touchdowns.

With Gurley now in the fold, this is sure to be a very entertaining position battle. After Gurley was drafted, Mason had this to say on Twitter.

Doubting me..? 🐸☕️

New York Jets – New general manager Mike Maccagnan decided to part ways with Chris Johnson after declining his contract option.

Despite Johnson’s departure, the Jets roster is loaded with capable running backs. But when it comes to a go-to workhorse, the Jets may be leaning towards Chris Ivory.

During Ivory’s first two years in New York, the 27-year-old rushed for 1,654 yards on 380 carries with nine rushing touchdowns. While those numbers are impressive, Ivory hasn’t proven he’s capable of carrying a heavy workload.

New York signed Stevan Ridley in free agency and traded for former Rams back Zac Stacy who will both be pushing Ivory for touches in training camp.

Arizona Cardinals – If not for a multitude of injuries at key positions, the Arizona Cardinals may have been a legitimate threat to compete for a Super Bowl in 2014.

However, one area where Arizona must improve at is on the ground. Last year, the Cardinals averaged only 81.8 rushing yards a game, which was the second worst in the NFL.

After a promising rookie campaign, Andre Ellington regressed drastically in 2014. Ellington only averaged 3.3 yards per carry this past season, but to be fair, he was nursing a foot injury and Arizona’s offensive line struggled to open up running lanes.

The addition of Mike Iupati should help up front and to push Ellington in training camp, Arizona selected David Johnson in the third round of this year’s draft. Johnson provides good size and he has an unique ability to be a legit threat in the passing game.

Heading into camp, you have to say Ellington is the favorite, but don’t be surprised if Johnson overtakes the top spot.

Dallas Cowboys – DeMarco Murray had a MVP type season for the Dallas Cowboys in 2014. Many attribute his success to the Cowboys offensive line. After all, it is the best unit in the league.

With that being said, Dallas may miss Murray more than they presume, but head coach Jason Garrett appears confident in his current bunch.

“DeMarco Murray did a great job for us last year. The business of the NFL comes into play and he’s not here anymore. That doesn’t mean we’re not going to be a running football team. We have guys in our locker room right now that we believe in.”

After acquiring Darren McFadden, most believe he’ll be the primary option in Dallas, but don’t be surprised if Joseph Randle steals the job.

Randle has shown flashes of brilliance, but the main thing with him is staying out of trouble off the field.

Jerry Jones believes Randle is heading in the right direction.

“He’s done things that weren’t smart, but he is smart, so you at least begin with the fact that he is understood, he is contrite, that he does recognize for the organization and everybody that he’s made some missteps, so all of that leads me to a perspective of a good player for us.”

No matter who gets the bulk of the carries, both of these backs should see success behind that amazing offensive line.

Oakland Raiders – With Darren McFadden in Dallas and Maurice Jones-Drew retiring from the game, the Oakland Raiders find themselves with a new duo in the backfield.

In hopes of resurrecting his career, Trent Richardson signed with the silver and black this off-season, but he may find himself backing up former UCF Knight Latavius Murray.

While Murray has a small sample size, the 6-foot-3, 225 pound back has shown potential of being a legitimate threat in this league. Due to his size and speed, Murray is able to run outside and in between the tackles.

Oakland is going to let this be an open competition, but something tells me Murray will end up being the starter.

In the midst of the glitz and glamour that comes with the training camp hype, these running backs will be putting their hearts on the line in hopes of being the top dog in the backfield.
