IT IS NO secret that the Eagles' offensive line failed to meet expectations in 2012 following multiple injuries and young players filling in for veterans on a moment's notice.

The Eagles addressed one need in April's draft when they selected tackle Lane Johnson with the fourth overall pick, the third lineman selected overall. Along with Johnson, the Eagles are preparing for the new season with tackle Jason Peters healthy and back on the field after missing the 2012 season with an Achilles' injury.

While Johnson and Peters hope to play a large role in the success of the offensive line, a few players are still fighting for positions as coach Chip Kelly acknowledges that no starter is yet set in stone.

"You never know what is going to happen," said tackle Dennis Kelly, who started in 10 games last season for the Eagles. "I have to do what I have to do to get on the field. It's kind of hard because playing last year so much, you want to come in and be considered the starter but with [Johnson] being drafted so high and him being that good of a player, you kind of accept it a little bit but at the same time I want to play well and be seen as a player that can start here. I just have to take it in stride and do what I have to do."

With the addition of Johnson, the Eagles hope to solidify an offensive line that allowed 48 sacks last season. Johnson, who saw time with the second team early in the Eagles' OTAs, practiced with the first team at right tackle on Tuesday with both Michael Vick and Nick Foles at quarterback.

"Working with the first team felt good," Johnson said. "We were getting the calls and communicating well while trying to be disciplined. I am just going in there and continuing to play as well as I can."

Guard Julian Vandervelde is in his third stint with the team after being released in 2011 and 2012. With center Jason Kelce perceived as the Week 1 starter against Washington, offensive line coach Jeff Stoutland told Vandervelde he could potentially become the team's backup center.

"I would welcome any job," Vandervelde said. "You always want that starting spot, but everybody is fighting for that spot and there are only five of them. I understand that I am new to the center position and I don't expect to blow anybody's mind out there, but I expect to get better every day. It's not my call but if at the end of the day I get good enough to win even a backup spot, I'd be happy."

Johnson, Vandervelde, Kelly and the rest of the offensive line will be competing for a spot in Chip Kelly's new system. The fast-paced offense Kelly ran at Oregon is something that each player has been trying to learn and adjust to during the first couple of weeks of OTAs.

"Coach Kelly's offense has different speeds and different types of tempos," Dennis Kelly said. "When I was at Purdue, [the offense] was predetermined. You kind of get used to [Kelly's offense]; you kind of see the benefits of it and why it works out. It was kind of a smorgasbord when Kelly was at Oregon."
