The Steelers had free agent Beanie Wells in for a physical earlier this week.
The Cardinals were reportedly "not optimistic" about the condition of Wells' knees before releasing him. Steelers doctors may have found something they didn't like as well, as he left club headquarters without a contract. It's fair to wonder if Wells might need a knee surgery before he finds a landing spot.
Also fair to wonder if he finds a landing spot if he has another knee surgery.
