Porter: I'm going to play with a chip on my shoulder for the simple fact that I love to go into a season any time someone doubts me. I’ve got to prove to myself that my game is still where I think it's at. I have no ill feelings towards Miami. ... But the chip on my shoulder now is hearing analysts saying, 'Does he still have it?' So that always gets me motivated and keeps me going."
Porter had 9.0 sacks for the Dolphins last season. Another former Steelers outside linebacker, Kevin Greene, had at least 9.0 sacks in five consecutive seasons after turning 33. Another 3-4 outside linebacker, Hall of Famer Rickey Jackson, did it four times after turning 33. They were among 27 players to accomplish the feat at that age in the sack era, according to Pro Football Reference.
Sacks aren't everything, but the Cardinals would be very happy with multiple 9.0-sack seasons from anyone, Porter included.
