Even though James Harrison (and Troy) didn't practice today again, they both still say they could still play on Sunday against the Jets. Whether or not that happens remains to be seen but with Harrison possibly out again, are you happy with Carter starting in his place and subbing in Jason Worilds? Or would you rather have Worilds in full time or Carter in full time?
IMO, right now the coaches are playing both guys to figure out who is the better candidate of the two, and to keep both ready in case more injuries happen like last year.
I don't think there's a clear choice between these two at the present; Carter is quicker and has good pass rush skills that need to be developed. Worilds is a good pass rusher right now with the experience edge, slight as it may be.
It's another reason why Woodley was dropping into coverage so much probably, neither of these guys can do it as well as he can...
