I'm about as excited for Richardson as I was for Deon Butler.
I'm struggling to recall the list of Seahawk players in recent history who began their careers with multiple years where they missed significant time due to injury then went on to be relatively injury-free later. Of course it's easy to recall the Marcus Tubbss, Russell Okungs, Deon Butlers, Percy Harvins, Deion Branches, I have to stop now my blood pressure has risen too high.
For some reason Anthony Simmons popped into my head but no, he played most of his games first 4 seasons and only broke down later on.
Carpenter might be on track but he was oft-injured due to fatness I'm not sure that's quite the same thing.
Does anyone remember players who overcame early significant (multi-year, multi-games-missed) injury struggles? I'm sure there have been some.
