"He's an unbelievable athlete, both running the ball and throwing it," Eagles coach Andy Reid said. "I'll think of something for him."
"He can definitely make a lot of plays," Eagles cornerback Sheldon Brown said.
The deal was announced during Thursday night's preseason opener against New England. Suddenly, no one cared about Tom Brady's first game in 11 months.
The 29-year-old Vick, once the NFL's highest-paid player, has been out of action since 2006. The former Falcons star was convicted in August 2007 of conspiracy and running a dogfighting ring, and served 18 of a 23-month sentence in federal prison. He also was suspended indefinitely by the NFL.
"I'm a believer that as long as people go through the right process, they deserve a second chance," Reid said. "He's got great people on his side; there isn't a finer person than Tony Dungy. He's proven he's on the right track."
Commissioner Roger Goodell conditionally lifted Vick's suspension on July 27, allowing him to sign with a team, practice and play in the last two preseason games. Once the season begins, Vick can participate in all team activities except games, and Goodell said he would consider Vick for full reinstatement by Week 6 (Oct. 18-19) at the latest.
The Eagles reached the NFC championship game last season under McNabb, but are still looking for their elusive first Super Bowl win.
McNabb has led the Eagles to five NFC title games and one Super Bowl appearance in the last eight years and was rewarded with a $5.3 million raise in the offseason. The Eagles tore up his old contract with two years remaining, and gave him a new deal worth $24.5 million over the next two seasons.
Philadelphia is a surprise landing point for Vick. It was among 26 clubs that said there was no interest in him, but that may have changed when backup Kevin Kolb strained a knee ligament earlier this week. Kolb's injury isn't serious and he's expected to return next week. The Eagles also have veteran A.J. Feeley.
"There won't be a quarterback controversy," Reid said.
Reid consulted with McNabb before signing Vick, who went to three Pro Bowls in six seasons with the Falcons.
"I pretty much lobbied to get him here," McNabb said. "He's no threat to me, not for Kolb. We had the opportunity to add another weapon to our offense."
When news of Vick's signing circulated in the press box during the first half of the Eagles' preseason opener against the Patriots, even the team's public relations staff seemed surprised.
The crowd quickly caught on at Lincoln Financial Field. Fans standing on the concourse were in disbelief. One guy wondered how quickly he'd be able to buy a Vick jersey. Another asked if this was a joke.
"It doesn't make any sense," said Michelle Harlan, a mother attending her first NFL game with a young son.
In a "60 Minutes" interview set to air Sunday, Vick accepted blame for not stopping the illegal dogfighting operation he bankrolled.
Vick said he feels "some tremendous hurt behind what happened."
