For a while, I was a little concerned that Quay had some of that DNA, too. Nowhere near to the degree that Burfict did, because Burfict was like a character from some horror movie, but Quay lost control a number of times that first year, and still somewhat his second. Gave away a number of first downs, and Matt was frustrated as hell with him for a while. Hopefully he's put that behind him now and outgrown it.
And Burfict did hand out some injuries. Blew up that Steeler RB's ACL, created a number of concussions with "defenseless player" and helmet-to-helmet hits... he just wreaked havoc. That guy is a batshit crazy sociopath.
