Why this insistence to "separate" anything? An illegal hit is an illegal hit. Lowering your head and launching at the other player's head is an illegal hit. Certain hits are made illegal because of the high probability of injury to the player who gets hit. When you consciously lower your head and launch at a defenseless player's head with the crown of your helmet like the video clearly shows Dunta Robinson did, he's clearly trying to injure the other player. No if, ands, or buts about it. Flagged as it happened, heavily fined afterwards. Why is it so hard to see?

Oh, and I am dead serious about the last question. Don't take it from me, take it from ex-players like Jason Taylor, who stated all NFL teams have money pools.
