But when healthy, Vick may arguably be the most explosive passer in the league. On Nov. 10, 2010, he became the first quarterback in NFL history to throw for 300 yards and four touchdowns and rush for 50 yards and two touchdowns. His touchdown-to-interception ratio in the past two years is almost 2-to-1 (39 touchdowns to 20 interceptions).. But injuries to his left (throwing) hand and ribs limited his ability to get much work in preseason games, and his health will be a closely-monitored topic in Philadelphia. The quote: Its tough when youve got a guy with the ability to break it with his legs and arm. So hes definitely a big challenge. He just keeps plays alive. Hes able to move around with his feet. He slings the ball like its nothing to him. It just flies out of his hand. Hes just a dynamic player. He creates problems for you because youve got to make sure the defensive line is staying in the lanes because it can be a big play if you leave [the field] open for him. Ravens cornerback Corey Graham, who had seven tackles and one pass defensed as a member of the Chicago Bears against Vick in 2009.
