The first step was accidental. When you step on something raised on a football field, there aren't many things it could be other than a body. The natural reaction when you step on something should be to take the weight off the foot and quickly remove it from whatever you are stepping on. He then proceeded to step on him again and then lift his other foot to place all weight on the foot smashing his ankle. It was dirty and he should be suspended for it. It was even more obvious when Rodgers reached up and whacked him one and Suh never turned around. Yeah, it was flagrant, intentional and suspension worthy, as are all of his actions.
