Vick has struggled in the first three games, having been responsible for nine turnovers - six interceptions and three fumbles. His passer rating is just 66.3.
None of that matters to Tuck. He knows what it is like to try to chase Vick around the field. Vick has rushed for 5,313 career yards, the most by a quarterback in NFL history.
"His speed really handicaps you as far as a pass rush," Tuck said. "You have to be very careful to keep him in the pocket and make sure he throws from in the pocket."
Tuck also said that Vick's speed can be both good and bad for the Eagles quarterback.
"He can utilize his speed sometimes more than he should," Tuck said. "That can be beneficial to us instead of him just staying in the pocket and throwing the ball sometimes."
That said, Tuck expects a difficult encounter Sunday.
"Vick is one of the most dynamic players who ever graced a football field," Tuck said. "Putting together a scheme for him is a day and night task."
Vick has not enjoyed a breakout rushing game this season. He has rushed for 94 yards (with a 4.5 average) and one touchdown.
The Giants are coming off a 36-7 win at Carolina, where they bottled up another pretty good running quarterback, Cam Newton.
The second-year quarterback threw three interceptions, no touchdown passes, had a 40.6 passer rating, and rushed for 6 yards and one touchdown on six carries.
Giants coach Tom Coughlin said that Newton's and Vick's offensive styles are somewhat different.
"Against Michael Vick we've had our problems here and there along the way in trying to defend his athleticism, his speed, the outstanding runner he is," Coughlin said. "He is a tough, hard-nosed guy and he certainly can take a hit and is an outstanding competitor."
Bradshaw starting. Giants running back Ahmad Bradshaw fully participated in practice. He was inactive last week with a neck injury. Coughlin said that Bradshaw would start.
Coughlin said that Andre Brown, who rushed for 113 yards and two touchdowns against the Panthers, would continue to see action. Brown has been cut by five NFL teams, including the Giants, who made him a fourth-round draft choice in 2009.
Receiver Hakeem Nicks who missed last week's game with a foot injury, is expected to play against the Eagles. For now he is practicing just once a week. . . . Other Giants who did not practice Wednesday were cornerback Michael Coe (hamstring), offensive tackle David Diehl (knee), cornerback Jayron Hosley (hamstring), and linebacker Keith Rivers (hamstring). . . . Safety Antrel Rolle, who has 20 tackles, had limited participation in practice because of a knee injury. . . . Domenik Hixon (concussion), defensive end Adewale Ojomo (hamstring), and cornerback Corey Webster (hand) fully participated in practice.
