Re: Defensive END play since Aaron Smith...
Keisel probably had his best season in 2012 and has played at a high level for several seasons
OTOH Ziggy Hood has not played to the standard and Heyward needs to step it up in 2013 or be labeled a bust.
I know the party line is it takes several years to learn LeBeau's 3-4 but at some point time is up
Clark figured it out immediately while Hampton, Troy and Woodley were at Pro Bowl levels by their second seasons
