I'd like to see Penny back. He had a historic run of 5 or so games when healthy, even behind an annually maligned Seahawks line. Penny had another game won for the Hawks that year, but Russell and the crap D gave away to the Bears. When healthy, Penny is a gamebreaker.
I was baffled why Penny got zero playing time in Philly, but now I'd have to guess it was the injury, and as someone pointed out, it's not just broken bones, but ligaments and other tissue that needed to recover. Bring him in to camp and whatever happens, happens. Injury settlement release during camp or 1,000 yard season, each within the realm of possibility. Sign AP as a consultant to give weekly pep talks to Penny and bring a belt.
