Found this on ESPN as Dobler was listed as one of the top 10 "villains" in sports. I was only a little kid when he played, but I can't image the Card having something that tough.
6. Conrad Dobler
The offensive lineman for the Cardinals, Saints and Bills in the 1970s and early '80s received the dubious honor of topping Page 2's list of dirtiest pro team players ever last year. He was a true villain who didn't care who he hurt, or how he hurt them. For example, he was so well known for biting (sound familiar?) that the Vikings requested rabies shots before playing against him. His unabashed dirty play resulted in several rules changes: no blocking a windpipe -- said Dobler, "When I hit a guy, I'll hit him in the throat ... he doesn't have any pads on his throat" -- and no leg whips.
Dobler got off cheap shots against Merlin Olsen and Mean Joe Greene -- in the Pro Bowl -- and Lions linebacker Charlie Weaver, among countless others.
But the cheapest, most juvenile of all came at the end of a 1974 game against the Giants, when the opposing players were shaking hands as the clock wound down. When Giant Jim Pietrzak attempted this ritual of sportsmanship, wishing Dobler good luck in the playoffs, Dobler punched him in the throat.
