I just heard it's official. Not that it would surprise any of us. But have not seen any news on it myself.
If so - and I'm sure it is - good luck Casey; you were a great Steeler. Never complained, was barely ever hurt, came up big when he was most-needed. From all accounts, he was a great guy and teammate. I remember Casey being our first round pick out of TX the first year I moved out of PA. Great draft pick; we can only hope the other first round DL picks pan out like this.
Kudos Casey. Have a great rest of your life as you move on to your "life's work."
