Nickname for Philadelphia Eagles QB Donovan McNabb. The second best QB in the NFL, right after Peyton Manning, McNasty has never finished worse than 11-5 when he has played a whole season. Five time Pro Bowler who became first QB to throw 30+ TD passes and less than 10 INTs in a season in 2004 while leading the Eagles to the Super Bowl. Will win a Super Bowl very soon. Rock on #5!
