He's not dirty. He's just obnoxious.
The Lions just lost two in a row at home, and he's yapping to the media on Monday about the Falcons' "karma"? Matt Ryan goes down for two plays in a game he wins, and that's all the bad karma the Falcons have coming? They must be the least dirty team in the NFL. What did the Lions do to have that 5-47 stretch?
He claims "I couldn't have been trash talking because there were trainers there," right before he drops that "karma" line... So you were too far away to trash talk when there were trainers there, but not when you're 800 miles apart? This isn't "old school tough," it's new school yapping in the style of overrated wide receivers.
The only karma in the NFL would be if the Lions end up tied with the Falcons for the 6th playoff spot.
