Costa's placement on the offensive line unknown

However, where Costa will be playing along the offensive line is still to be determined. The Cowboys used their first-round draft pick on center Travis Frederick last month. Costa had been the team's first-team center, starting three games last season and all 16 games in 2011.
"I came in the league and every day was a fight and still every day is a fight, so I look at it as just competition," Costa said Wednesday. "I think competition really brings out the best in everyone, which coach has talked a lot about with our team. There's going to be that. It's good. It really brings out the best."
Costa, 25, does have experience playing guard, something he did during his sophomore and junior seasons at Maryland. Would that be an option for him with the Cowboys?
"I mean, I've played guard before," he said. "I've played center. I guess wherever the best fit is."
Costa said he would be welcoming to the former Wisconsin standout, calling Frederick "a good player who can help our offense and help our team win."
"You don't get anywhere by being a certain way as an older guy to a younger guy," he said. "You got to treat everybody with respect, as a teammate and especially a guy who's in the o-line room. We take our group serious. We're a tight-knit group in there, so it's important."
Entering his fourth NFL season, Costa says he is 100 percent healthy. He missed 13 games last year because of a back injury and a season-ending dislocated ankle.
So, back to that contract extension that will keep him with the Cowboys through the 2014 season. Why did he agree to the deal?
"I wanted to stay in Dallas," he said. "Everything they do is really a first class organization. Being with Bill Callahan as the offensive coordinator/offensive line coach is huge. I think he's one of the best in the league. I feel like I can get that much better being with him.
"We have a great group of guys in Dallas. A lot of selfless guys. I feel like we have a great chance to win here as well."
