Ward was a good player, cheap shot artist, but a good player. I highly doubt he would knock Burfict out but it would be interesting to see him try.
blocking is not being a cheap shot artist. Playing hard is not dirty either...twisting players legs after the tackle and going at a QBs knees, that **** is dirty.
Defenses hated Ward because they had gotten used to playing without having to watch their surroundings for players like him. There is a good video of Harrison chasing a play and a cowboy receiver trying to crack back on him. Being the player he is, Harrison saw the guy coming and knocked him into the runner causing the tackle.
