The have given us some ugly offensive performances this season, but it's probably safe to say that none of them were uglier than what happened on Sunday in Philadelphia. During Chicago's 31-3 lo s to the , the Bears' offense basically set football back 50 years. As matter of fact, the Bears' offense was so bad against Philly that it was literally going backwards at times. Chicago's three running backs -- , and -- actually combined for yardage in the Bobby Jenks Jersey blowout lo s. Of the Bears' three running backs, Jordan Howard was the star -- and we use that term loosely -- of the game as he carried the ball seven times for six yards. When you throw in the numbers from Cunningham and Cohen, the Bears three backs finished with a combined 10 carries for negative-6 yards. The only reason the Bears didn't finish with negative rushing yardage is because managed to rush for 12 yards on four scrambles. The Bears' team rushing total of six yards actually set football back further than 50 years. The six-yard rushing performance was the Bears' worst since 1952, when they totaled exactly one yard on the ground in a game against the . As bad as the Bears have been this season, running the ball has been one of the few things that they were able to do well. Going into Week 12, the Bears were ranked fifth in the NFL in rushing yards per game. That number is going to drop big time after Sunday's performance. Overall, the Bears only totaled 140 yards in the game, which was their worst showing in seven years. The Eagles definitely deserve some credit here for shutting Chicago down, but John Fox also deserves a large part of the blame because we're 12 weeks into the season and it's still not exactly clear what the Bears are trying to accomplish on offense. I mean, you could make the argument that the Eagles' team celebrations were more organized than the Bears offense on Sunday. The are Yolmer Sanchez Jersey ELECTRIC. NFL (@NFL) The Eagles. defense was celebrating a lot in the first half, when they held the Bears to 33 yards and a total of zero first downs. With an offense that looks lost and the Bears on a four-game losing streak, it wouldn't be surprising to see the Bears make a coaching change if Fox doesn't find a way to win two or three more games down the stretch this season. Let's get to the rest of the grades. Bears: F It's still up for debate, but the Bears might have actually played the worst first half in NFL history. Of Chicago's six po se sions in the half, the Bears punted four times, mi sed a field goal and threw and interception. Also, they only totaled 33 yards and didn't record a single first down. That's about as ugly as it can po sibly get for an NFL team in one half of play. Eagles: A- The scary thing about the Eagles is that they won this game by four touchdowns despite the fact that they turned the ball over three times. The other scary thing about the Eagles is that coach Doug Pederson has decided to eschew the conservative ways of most NFL coaches and get crazy. The Eagles went for it on fourth down a total of four times in this game and converted three of them. Oh, there's actually another scary part, too: The Eagles only surrendered 140 yards in the game, which was the team's best defensive performance since 1996 when they only gave up 121 yards to the . Bills: B+ wasn't great in this game, but one thing he didn't do was throw five Jace Fry Jersey interceptions. Taylor threw for 183 yards and one touchdown and then let the ' defense do the rest. The Bills completely bottled up , holding him to just 17 yards, which was the rookie running back's lowest total of the year. The Bills defense needed a game like this after getting lit up for 54, 57 and 34 points over the past three weeks. Chiefs: F It seems that the wheels have now completely fallen off the wagon in Kansas City. The only totaled 57 yards in the first half, and somehow, things only got worse after that. If there's a panic button in the Chiefs' locker room, someone needs to push it now. As bad as the Chiefs have been in recent weeks, this game might have been rock bottom: They lost to a reeling Bills team and for the first time all season, didn't produce at least 250 yards of total offense (236). Panthers: B was off his game in New York (11 of 28 for 168 yards), but that didn't matter for the because they found plenty of other ways to score points that didn't involve their offense. might have made the biggest play of the game in the fourth quarter when he returned a fumble 34 yards for a touchdown that gave Carolina a 26-20 lead. Actually, the biggest play for Carolina might have come on the next series when returned a punt 60 yards for a touchdown that gave Carolina 32-20 lead. Actually, they were equally big plays because the Panthers needed both scores as they fought to Chicago White Sox Jersey hold off a feisty Jets team that was leading this game early in the fourth quarter. Jets: B almost did enough to carry the Jets to a win by himself. The second-year receiver caught six pa ses for 146 yards and two touchdowns, which was especially impre sive because it came against a Carolina defense that was ranked fourth against the pa s going into Sunday's game. The Jets arguably outplayed the Panthers, but they watched the win slip out of their hands during a 131-second span in the fourth quarter where the Panthers scored two non-offensive touchdowns (a punt return and a fumble return). If Jets fans were handing out grades, they'd probably give the officiating crew an 'F' for overturning a controversial touchdown in the fourth quarter. Browns: C If the could have figured out how to finish off a drive, they might have been able to pick up their first win of the year. The Browns drove inside of the ' 10-yard two times in this game and didn't come away with a touchdown either time. Of course, the fact that the Browns struggled in the red zone was only about 40 percent of the reason they lost. The other 60 percent revolves around the fact that Cleveland couldn't stop a Bengals offense that went into Sunday's game ranked dead last in yards per game and 29th overall in points per game. At one point, the Bengals scored on five straight po se sions, and you're never going to win if you let the NFL's worst offense score on five straight po se sions. Bengals: B+ For the first time all Jeff Keppinger Jersey year, the Bengals actually got some production from their ground game. Rookie (114 yards) led a Bengals rushing attack that totaled a season-high 152 yards. The Bengals might want to make multiple copies of Sunday's game plan and just go ahead and use it for the rest of the season, because if we've learned one thing during 's career, it's that the Bengals are nearly unbeatable when he gets some help from the ground game. Since drafting Dalton in 2011, the Bengals are 20-1-2 when they rush for 150 or more yards in a game. Dolphins: C- It's hard to say if is an improvement at quarterback for the because he never really got a chance to prove himself t
