So you're saying they should just let the receiver catch the pass, make two steps, then hit him? Where was Mitchell supposed to hit the guy? Smith is 5'9" and was crouching down.. Even then, it was still shoulder on shoulder contact.. What trucking replay did you watch? If anything, Mitchell should have been rewarded for hitting such a tiny target without knocking his head off. Brown's hit didn't draw a flag because it didn't look violent enough to the refs.
