A few weeks ago when the Steelers and Bengals played there were $140,000 in fines handed out to players on both sides. The teams clearly dont like each other and Im not saying the Steelers are innocent because they can get rowdy also, but the Bengals (mainly 2 or 3 players) have chips on their shoulders. In that game Burfict had 3 separate persoanl fouls called on him including one where he intentionally dove at Roethlisbergers knees. Half of that $140,000 in fines went just to Burfict. He was so out of control that before this game there was a story that he promised his teammates that he would keep his composure. You dont do that unless you are constantly losing your composure. Then he obviously did it over and over again this time.
Hes also the one who tackled LeVeon Bell and ripped his knee to shreds in mid season. Although it was a legal tackle, apparently afterwards, he and other Bengals were clapping and celebrating.
