The Steelers are a great team always in the thick of the playoff race. They won at least one Super Bowl without ANY of these guys and won two without most of them.
They are a great team and let the people that are not a necessity leave for greener pastures. The replacements for these guys all do a great job, but to be honest, I know how the Steelers are, and I don't expect them to pay top dollar for players when they already have the replacement on the team ready to go.
That being said, we did not sign anyone in Free Agency to replace these players, so had the Steelers decided to keep them, they would have only been that much better.
Is there anyone I forgot? Add their name to the comments, and I will add them to the list.
