Here's the specific details that just might rekindle the Panthers fire when the Saints return to Charlotte later this season:

Goodell: Saints targeted Panthers in 2010 - NFL Nation Blog - ESPN
"In that game,’’ Goodell wrote. "Three Carolina players were seriously injured: running backs Jonathan Stewart and Tyrell Sutton, who were literally carted off the field with a head/neck and ankle injury, respectively, and quarterback Matt Moore, who was later placed on injured reserve, unable to return for the remainder of the season, with a torn labrum. These all satisfied (defensive coordinator Gregg) Williams’ definition of cart-offs: ‘big hits that resulted in an opposing player leaving the game due to the hit."

That is pretty specific and enlightening information. At this point though I'm not sure how much this moves the needle given both teams are at 1-4. They wanted more detail so I guess Goodell is finally showing his hand. I'm betting in the end we wish he didn't.
