Cardinals fighting to avoid historic letdown

Posted by ESPN.com's Mike Sando

GLENDALE, Ariz. -- The Cardinals are trying to avoid becoming the seventh team in NFL playoff history to lose after leading by at least 18 points.

They led 24-6 at halftime. They now trail, 25-24, with 10:45 left in the fourth quarter. The 2006 Colts, 1972 Cowboys and 1985 Dolphins also overcame 18-points deficits to win in the playoffs.

The 1957 Lions overcame a 20-point deficit to beat the 49ers. The 2002 49ers overcame a 24-point deficit to beat the Giants. Those comebacks trail only the 1992 Bills' legendary comeback from a 32-point deficit against the Oilers.
