The Latest from Marty and Juan

Offensive coordinator Marty Mornhinweg and defensive coordinator Juan Castillo spoke to reporters in the NovaCare auditorium Friday, as the Eagles prepare for Monday's game at New England.

Highlights:

*Mornhinweg confirmed to a wider audience something he had said to a couple of us earlier -- that the idea of Chris Polk as a fullback has been discussed. Negatives are that Polk weighs less than 225 pounds, and he didn't get drafted because teams were concerned about his loose right shoulder. Right shoulder klind of a big deal for a fullback. But Polk is a hitter, no question.

Polk said afterward that he is familiar with the discussion, though he hasn't been asked to learn any of the fullback plays. He said he will do anything he can to make the team. He said he didn't think his shoulder would be an issue.

*Mornhinweg said gargantuan rookie offensive tackle Dennis Kelly is having "just a terrific camp." The Eagles have used Kelly at tackle and at guard -- Todd Herremans' long run at guard before shifting to tackle last year seems to have made the world safe for 6-8 guards.

*Morhinweg said that although veteran Qb Trent Edwards doesn't get that many practice reps, he still has every chance of making the team. Which doesn't seem to make a lot of sense, really, but that is what he said.

*Castillo said getting off the field on third down would be a big focus Monday.

*Castillo again defended second-year safety Jaiquawn Jarrett. "JJ will knock your block off," Castillo said.

*Castillo acknowledged that "you can't keep all" the defensive linemen the Eagles are juggling. This is relevant because just about all of them seem to be able to rush the passer.
