It was initially thought of as a starting competition between Baltimore defensive ends Arthur Jones and Pernell McPhee.

To a degree it still is. Both would prefer to start in the season opener against Cincinnati on Monday night, but their contrasting styles may make it a moot point because both figure to earn enough playing time in different packages to utilize their strengths.

Jones is tough against the run, which will come in handy with the Ravens forced to defend Bengals running back BenJarvus Green-Ellis. A year ago, McPhee showed his strong suit is his pass rushing ability. He tallied six sacks in third down situations coming off the bench.

In addition, the two of them have practiced at multiple techniques and could wind up on the field at the same time, given the situation.

"We have a lot of roles, lot of jobs, from goal line, to run to pass," Jones said. "We're both going to get a lot of playing time."

McPhee compared the situation to how it was in 2011, when Cory Redding was Baltimore's starting defensive end. Redding would come off the field on third down and McPhee would enter to rush the passer.

McPhee's snaps were limited in 2011, though, and he expects more this year.

Known as a situational pass rusher last year, McPhee's gained 10 pounds of bulk to aid his defense against the run.

"It gives me a little thump in the trunk," McPhee said. "It holds me down a little bit but it's all about dealing with your heart and your mindset. It doesn't matter how much you weigh, it's about your mindset and going out there and competing."

The Bengals offensive line is a big group, averaging 318 pounds per person (with right tackle Andre Smith leading the way at 335 pounds.) They finished fourth in sacks allowed in 2011, giving up just 25 for the season.

With QB Andy Dalton and WR A.J. Green entering their second NFL seasons, it will be a challenge for the Ravens front seven to generate pressure in Cincinnati's backfield.

Jones and McPhee offer different attributes along the defensive line. Baltimore will need both to play well when given the opportunity if its to disrupt what Cincinnati wants to do offensively.

"We have a great opportunity to send a message early in our division," Jones said. "They have a big, physical offensive line which has already been known. We know it's going to be a dog fight."
