The Packers lost someone because the idiot who hit him seemed to think he was a train colliding with a small car and he wasn't hit below the knee. Where someone is hit barely matters- the knee is a POS design- the four muscles that make up the quadriceps attach to the kneecap and only one tendon attaches that to the top of the tibia. ONE stinkin' tendon and the only thing that keeps the kneecap aligned is a peak on its backside and the groove in the ends of the bones.
