Incognito's explanation makes sense...this happens all the time when the ball pops out. Smith doesn't have a squeaky clean reputation either.
“I have seen the video,” Incognito said. “Once the ball was fumbled I grabbed his legs to stop him from recovering the fumble. It’s clear that I wrap my arms around both his legs. I was trying to keep him from scrambling to the ball.
“After the ball was recovered I felt him kicking me. I was trying to protect myself. Kind of like a turtle in a shell. At no time was I turning his ankle. My intent was to keep him from getting to the ball.”
But Incognito was pragmatic. “Obviously in a case like this I have no ground to stand on [because] of my reputation,” he said. “There is no evidence of me trying to injure him. The reason I’m seen holding onto one of his legs [because] he started kicking me in the arm and neck the the other. I had both legs in my grasp. The fact of the matter is I’m laying on his leg. There is no twisting motion whatsoever. He is clearly kicking me in the neck. Talk about dirty?”
