While McNabb's style is effective during the regular season, NO "scrambling" QB has ever won a Super Bowl to my recollection. For such a QB, once Option "A" is taking away, Option "B" had better be good enough to win the Big Game in the NFL. McNabb's "Option "B" obviously isn't.
Pure scramblers, no. But Staubach, Stabler, and Elway were great QB's who also happened to be great scramblers.
Precisely!
NO scrambling/running QB has ever won an NFL Championship!
By the time scrambler/runners do win like Staubach and Elway, they have finally gotten the giddy-up out of their brains and ONLY use that ability to get open to throw. They become throwers first and runners second.
Early in their careers they scramble and run and force passes which become intercepted when receivers are forced to scramble to get open and have the ball thrown to them in awkward positions.
Later on they realize that perhaps taking a sack or throwing the ball away is perhaps a better idea that retains possession and/or field position. It doesn't take them out of field goal position and gives the rest of the team a chance to win, which is much easier to do when your team has the ball.
McNair is a much better QB when he is hurt and cannot run, although he is reaching the point where he realizes perhaps running is not in his or the team's best interest, even if he can get a first down doing so.
McNabb was a better QB when his ankle was broken and he was thinking pass first, run second. Elway lost what, 3 SB's before he got wise to how QB's win games. Same with Staubach. And especially the same for Steve Young. He got his MVP for 6 TD passes in the SB NOT for getting a first down running. Fran Tarkenton never learned.
Norm Van Brocklin said it best. "Quarterbacks should only run when in fear of their life."
Terry Bradshaw, closest QB to ever be a scrambler and win a SB. However, nobody ever thinks of or describes Bradshaw as a runner/scrambler.
Which as a Falcons fan you have to wonder. If Michael Vick is the answer - the Falcons obviously don't understand the question.
