Elvis is basically a one-man pass-rush and our DT's never collapse the pocket, EVER.
Considering teams can pretty much zero in on Elvis, I think what he's achieved this year has been remarkeable.
Williams is just a freak of nature though, unfair comparison.
He's not saying Elvis Dumerville is better than Mario so I'm not criticizing the poster. But aside from Okoye, the rest of our D-line hasn't been all that great. Anthony Weaver never pressures the QB from the other DE spot and Maddox, TJ, and Earl Cochran are off and on as DTs. Mario is what has made the D-line look as good as they have IMO.
