I saw that famous Mike Curtis sideline clothesline hit! WOW! The guy was tearing down the sideline, police in pursuit, and Curtis (#32, Colt middle linebacker) stepped up from the bench and NAILED him in the throat with a roundhouse forearm!
BOOM!!
The guy's head stopped right there, his legs and body flew out to the horizontal, and he landed on his back out cold.
I was just thinking about that hit the other day. The guy wasn't really "tearing" down the sideline. IIRC, he had a longish coat on, and was kinda galumphing.... But he did go down real quick.
