PHILADELPHIA (CBS) — It’s being called the biggest game of the season. Sunday’s Eagles game against Dallas has fans in fight mode.

“We bleed green, we’re die hard,” says Edith Ball, one of the many fans at an Eagles rally at Chickie’s & Pete’s in South Philly on Friday.

“This is as big as it gets for a regular season game,” says Rob Ellis.

Ellis, along with Anthony Gargano from Sportsradio WIP, held their show here and hosted a pep rally. And Ellis says Sunday is a “do or die” game for a couple of reasons.

“The energy, regardless, is when you have a game that’s winner-take-all that gets you in the playoffs. If you lose, you go home…it would be huge, but you add that cherry on top of that Sunday that is the Dallas Cowboys in this town, the most hated rival,” Ellis says.

Fans we spoke with wanted Cowboys quarterback Tony Romo to play.

“So we can beat Romo and get him out the way!” explains Chris Paul.

Every season, fans believe in the birds but end up heartbroken — something sports psychologists say is all part of picking a team to root for.

“Being a fan is a package deal when you allow yourself to go in, all in, and get really excited — there is a chance for disappointment,” explains Dr. Joel Fish.

Overall, folks say it’s been a better season than they were expecting.

“Chip Kelly is doing a wonderful job – this is the best offensive line I’ve seen in years,” Chris Paul says.

“It turned out to be a better year than I thought it was going to be. Foles is the real deal,” adds fan Matt Kress.

But we’ll all have to wait and see what happens Sunday.
