I only expect a highly-touted DE, such as Mario, to produce and to do it on a consistent basis....not be quiet and invisible for several games and then run into a string of sacks against weak teams like the Rams or Raiders, etc.
Freeny and Ware are better DEs than Mario.
Put Ware on this Texans defense and he gets 127 sacks and is banned from the NFL for sexual assault on the field of play.
And in case somebody wants to scold me, again (and not pointing fingers at you, rey), let me say this: This defense, with a new d-coord and better secondary players and a Defense-heavy draft that produced JJ Watt, is outgrowing Mario Williams. Not entirely, obviously. I mean to say that this defense as a whole unit is capable of wreaking havoc with or without Mario.
We've practically had no other "good" defensive players outside of Mario Williams, Dunta Robinson, and DeMeco Ryans when he's not hurt or making "it's juts another game" comments. It's easy to understand why so many fans are still thinking Mario is just mislabeled by the haters, etc. Whatever. The guy is not "great," and I won't buy the argument from some who claim he's a top tier guy. He's close, but no cigar, IMO.
