During the Giants’ five-game winning streak at the start of the season, Eli Manning didn’t have a QB rating lower than 93.5. In the Giants’ current three-game losing streak, Manning hasn’t had a QB rating higher than 61.0, which includes his 55.7 mark in New York’s embarrassing 40-17 loss to the Eagles in Week 8.

To say that Manning hasn’t been good lately would be an understatement. In the loss to Philadelphia, he was 20-of-39 for 222 yards with one touchdown and two interceptions. And given how inaccurate he was most of the day, he could have been intercepted at least two more times.

In his last three games, Manning has thrown six interceptions to just three touchdowns. The mistakes he’s made aren’t typical of a veteran quarterback that has a Super Bowl ring – they’re more akin to a first year starter with little to no experience. He looks like a player with zero confidence and he doesn’t appear to trust his own decision-making.

While the Giants have more issues than just Eli (the secondary has also played poorly and the team continues to struggle with injuries), they have to be concerned with his play. New York has needed him to put the team on his shoulders and carry them to victories and he hasn’t. And based on the way he’s played the past three weeks, there’s serious doubt he’ll be able to break the Giants out of their funk without a lot of help from his defense and running game.

That said, it’s only been three games and while he has looked horrible in those three outing, he looked great in the first five games of the season. The problem is that the Cowboys were the only team with a winning record that the Giants have beaten this year. Eli’s impressive numbers have come against teams like the Redskins, Bucs, Chiefs and Raiders, while he has struggled against tough opponents in the Saints, Cardinals and Eagles, respectively.

With David Carr listed on the depth chart behind Manning, the Giants won’t consider a QB change. But the entire team better start picking up their play before the season starts to slip away from them, and it all starts with Eli.

When the New York Giants placed wide receiver Plaxico Burress on the non-injury football list earlier this week and effectively ended his season, everyone said all the right things. The players said they could win with or without him and the media said the Giants were all about the team – both true.

But nobody could say following their 20-14 loss to the Philadelphia Eagles on Sunday that the Giants couldn’t have used Burress. Eli Manning was just 13 of 27 for 123 yards and a touchdown, while no Giant receiver had more than four catches or 40 yards.

I don’t want to take anything away from the Eagles’ defense, because they blitzed and swarmed Manning the entire game. They also should have had at least one interception, but Asante Samuel and Brian Dawkins collided with each other and the pass fell to the ground.

That said, Manning looked completely out of sync with his receivers and Domenik Hixon dropped a perfect pass that could have been a touchdown. And once Brandon Jacobs left the game with a knee injury in the third quarter, the Giants could have really used a playmaker like Burress to breathe life into their offense.

Burress doesn’t deserve to be playing right now and it’s only fair he’s being punished for his selfish actions. But the idea that the Giants are a better team without him still remains to be seen and their loss Sunday proves that. They’re still the best team in the league and they will bounce back from their defeat. But it’ll be interesting to see whether or not the offensive woes that were on display on Sunday will reappear in the postseason without Burress in the lineup.

As for the Eagles, this was a massive win and it keeps their slim playoff hopes alive. With the Saints’ win over the Falcons, the final NFC Wild Card spot is up for grabs and if Brian Westbrook (203 total yards, 2 total touchdowns) and the Eagles’ defense plays as well as they did against the Giants, than Philly’s playoff hopes are far from dead.
