Steelers GM Kevin Colbert was "emphatic" Thursday that NT Casey Hampton (ACL surgery) will be on the 53-man roster in 2012. Hampton is due a $4.89 million base salary and counts $8.1 million against the salary cap, but the Steelers firmly believe nose tackles recover better from ACL surgeries than skill-position players. That's undoubtedly true, but Hampton is no lock to turn in a 16-game season after tearing the ligament in early January. He's a candidate to open the year on PUP.
