DESEAN JACKSON didn't back off his contention, voiced earlier this week on the NFL Network, that it would be better for the Eagles to know who their quarterback is going to be, heading into training camp.

But Jackson, speaking at Saint Joseph's before a screening of his documentary, "DeSean Jackson: The Making of a Father's Dream," said he understands why new coach Chip Kelly isn't ready to make such a declaration.

"I wish I could know, but at the end of the day, that's the coach's decision," Jackson said. "I'm going to play that how it goes. I think we have four great quarterbacks, with [Michael] Vick, [Nick] Foles, [Matt] Barkley and [Dennis] Dixon . . . I think throughout the offseason, everybody did everything the right way, everybody practiced hard, everybody was there, accountable, and did the things they were asked to do . . . moving forward, we just look forward to knowing who will be [the starter], because that'll definitely help us prepare better going into the season.

"He's never been a coach of ours; of course, with a new system, he's going to want to know who best fits the system."

Jackson reiterated that all the QBs had worked hard to learn the system, read defensive keys and "get the ball where it needs to go," so he would be happy with any of them.

Kelly said at the end of minicamp that he wants to see the quarterbacks play in preseason games before he picks a starter. Vick and Foles are the main contenders.
