As Barry Horn notes in his DallasNews.com Sports Media Blog, there's a great chance the season finale between the Cowboys and Eagles will be moved to Sunday night. The way it's looking now, that game will probably have playoff implications for both teams.
But if the Colts are still going for an undefeated season (against the Bills), that game could also be in the mix. When in doubt, go with the big-market teams. A Cowboys-Eagles game with something on the line seems like a no-brainer.
