2011: vs. Titans (3-30), @ Saints (17-45)
2012: vs. Giants (7-36), vs. Broncos (14-36)
2013: @ Cardinals (6-22), @ Saints (13-31)
2014: vs. Steelers (19-37), ?
The trend so far has been one blowout early in the year, and one late in the year. After every blowout early in the year, the Panthers have rebounded to play a much better game, but didn't win following a blowout until 2013 (vs. Rams after being blown out @ Cardinals).
It will be interesting to see how the Panthers respond after this blowout. Sure, they got blown out, but it wasn't like they were outclassed by the Steelers. They were due for a bad game after a long run of really great games. This just follows the trend and it's better to have this happen and be 2-1 than 0-3. The future is still bright, but I hope the Panthers can recover and win a big road test against Steve Smith and the Ravens (who the hell thought I'd be saying that last year....?)
