OK, it helps when his defense scores a huge momentum touchdown at the end of the first half - and then hangs on to withstand a final, furious threat at the end of the second half, surviving only when Dallas' 12th penalty of the game negates what appeared to be the winning score.
DeAngelo Hall returned a fumble 32 yards for Washington's only touchdown, and /*McNabb*/ completed 15 of 32 passes for 171 yards in his Redskins debut Sunday night in a season-opening, when-do-we-exhale 13-7 win over the Cowboys.
It was also the Redskins' curtain-raiser for Mike Shanahan, and the longtime Denver Broncos coach watched his defense keep the Cowboys at bay when it mattered.
The Cowboys (0-1) moved inside the Redskins 40 on three of their first four drives and didn't score a point, but the drive everyone will remember is the last one, which came after Graham Gano made a 49-yard field with 1:50 remaining to give the Redskins (1-0) a 13-7 lead.
After the kickoff, the Cowboys started at their own 19 with 1:45 left. They converted a fourth-and-10 at Washington's 43 when Tony Romo hit wide-open Miles Austin over the middle for a 30-yard gain with 12 seconds to go. Three plays later, Romo had only 3 seconds left on the clock. He scrambled to find Roy Williams open in the end zone.
But, while Williams and the Cowboys were celebrating, the official was calling Alex Barron for holding Redskins linebacker Brian Orakpo, negating the score and providing a fitting end to a game in which the Cowboys made mistake after mistake. Barron was starting because Marc Colombo missed the game with a knee injury.
McNabb was playing the Cowboys for the third straight game, the first player to do so since the 1970 merger. His /*Eagles*/ lost to Dallas 24-0 to end regular season in 2009, then 34-14 the following week in playoffs in his last game with Philadelphia before the Easter Sunday trade that sent him to the Redskins. He now trails Romo 5-3 when the two quarterbacks go head-to-head.
