I think they're notable in this respect. Two were veteran pass rushers (Burgess was much younger), but all three had an established rep as an "explosive edge rusher." All three recovered enough explosiveness and change of direction to put up elite pass rushing stats over a 2-3 year period.
I'm not arguing that it's a sure thing that Suggs returns to full form or that, if he does, he'll do so before 2014. I'm arguing that what's been a common knee jerk response over the past two years -- that a torn Achilles tendon is a near death sentence -- is easily refuted by what I believe to be very reasonable data points.
He's be 31 by then, or Ellis' age. Now taking away the other 2 guys, the only comp is one guy. That seems like more of an outlier if anything. Maybe it's early to call Suggs done, but it's not unfair to say he's got a huge uphill battle to get back to where he once was.
I don't think age 31-32 should be considered the age of doom for a defensive end.
Quite a few elder statesman on the list of elite football players with double digit sack seasons after age 30. Jared Allen will be 30 this year. So will Demarcus Ware. Neither show signs of slowing down yet. John Abraham has 46 sacks since turning 30 and over 20 since turning 32. Kyle Vanden Bosch had eight sacks at age 33 last year. Joey Porter had almost 30 sacks during his age 31 and 32 seasons. Jason Babin had 18 at age 31 last year. Michael Strahan, Kevin Greene, Reggie White, Bruce Smith, Jason Taylor, Chris Doleman, Richard Dent -- all effective into their mid-30s.
None of those players are post-Achilles. But I'm highlight them to show that -- should Suggs return to form -- elite pass rushers can remain effective into their early and mid 30s.
If you don't buy the Burgess/Peterson comps, which I believe are reasonable for the same age-related reasons we're discussing now, you might also consider Takeo Spikes who has been effective well into his mid-30s after his Achilles tear.
