Chip Kelly will finally see his players on the field this week. The Eagles will hold their first minicamp from Tuesday to Thursday, offering Kelly his first glimpse of the team actually participating in activities that resemble football.

The voluntary veteran minicamp is an important landmark in Kelly's first season with the Eagles, and especially as he begins to evaluate his roster. For Kelly's first two months, he reserved judgment on his team because he was not able to talk football with the players or work with them. On April 1, the offseason program commenced, but it has been limited to meetings, conditioning and weight training.

"This is going to be huge," wide receiver Riley Cooper said Sunday. "This is his first look at all the players, and just kind of get his assessment of them."

Even Kelly has conceded that game film provides only so much information. So for every player - those who excelled under Andy Reid, those who struggled, and those who are new to Philadelphia - their true first impression will be made this week.

"First impressions are always big," safety Nate Allen said. "But at the same time, they realize we're putting in a whole new system. There's going to be mistakes. It's going to be going 100 miles per hour."

Cooper and Allen were among six Eagles players who signed autographs and posed for pictures at Sunday's Huddle Up for Autism event at Lincoln Financial Field.

The Eagles distributed 5,000 tickets to the annual carnival that aims to raise awareness of autism. The other players in attendance were safeties Kurt Coleman and Colt Anderson, tight end Clay Harbor, and linebacker Chris McCoy.

The sentiment from the players was genuine excitement about this week's minicamp. Even though it is voluntary, every player on the roster is expected to attend. And they can anticipate a faster pace than what they were used to in the past.

"I think it's going to be completely different," Cooper said. "It's going to be so high-tempo. . . . It's a completely different outlook, a completely different offense."

Cooper, who played for Urban Meyer at Florida, said he knows what to expect with the tempo. Players have become used to the pace during the last two weeks, when workouts were intense and included considerable running.

"Reid always wanted everything to be quick, but this is going to take it to a whole new level," Coleman said. "I noticed that's the way we've been training with our strength staff. We've been doing a lot of running - a lot of running."

However, the limitations of this minicamp must also be understood. Individual player instruction and team practice on a "separates" basis is permitted, but no live contact is allowed and there cannot be offense vs. defense team drills.

Plus, there are three more organized team activity workouts and one full-team mandatory minicamp on the schedule during the offseason. Then there's training camp and preseason. So even though this week is an important first impression, it will not be a decisive, lasting impression.

"Don't get me wrong; this week is a big week, but this isn't training camp," Allen said. "We're not trying to make the team off this one camp. I feel like this camp is going to be a lot teaching and a lot of learning. It's still going to be fast. Everyone's going to be playing fast, but we understand there's probably going to be some mistakes."
