IRVING, Texas (AP) -Fans aren't alone in wondering whether the Dallas Cowboys are good enough and mentally tough enough to beat the Eagles in Philadelphia on Sunday.

Linebacker Bradie James and receiver Roy Williams are wondering the same thing.

The Cowboys were humiliated 44-6 in Philadelphia in last season's finale, a loss that kept Dallas from making the playoffs and put the Eagles into the postseason.

Now the Cowboys are headed back, and they are rolling on offense, defense and special teams. They've won three straight and the teams are tied for first in the NFC East. The game also will be in the Sunday night, prime-time spotlight.

James says how the Cowboys perform will speak volumes about them. Dallas hasn't won a playoff game since 1996.
