Eagles coach Chip Kelly spoke with reporters before this morning's practice. On some topics, he was less than forthcoming. Asked a generic question about how he chooses the signs the team uses to signal offenses and defenses, Kelly said "No ... Honestly, no, we can go on to something else. I'm not going to explain why we go through that whole thing."

Asked if he had some special scientific approach to road trips, with Saturday's preseason game at Jacksonville looming, Kelly said: "We fly, if at all possible."

But on other topics, Kelly was willing to engage. Kelly was asked what he has learned about quarterback Michael Vick since taking the job in January.

"What I've learned about him is how passionate he is about this game. He has not missed a day ... you listen to our strength and conditioning guys, I asked then the other day, from top to bottom, if you can rank our guys, and he was No. 1 in terms of his attitude, work ethic, helping other players, everything in terms of weight room, off-the-field things," Kelly said.

Kelly also addressed the decision to bring coaching intern and three-time Eagles Pro Bowl left tackle Tra Thomas aboard as a fulltime staff member, assisting offensive line coach Jeff Stoutland:

"Yeah, Tra was outstanding. He came in through the Bill Walsh Minority Intern Program, and it really started in the summer, but when we got a chance to talk to Tra about doing it, the next day he was here," before the program was scheduled to begin, Kelly said. "Extremely dedicated, one of the all-time great Eagles ... One thing about Tra, when you sit there and watch film with him is just how much he's studied tape on his own and what he learned about the game, and I think he's imparted that to a lot of the young linemen we have ... I think he's got a bright future in coaching."
