This post nails it correctly IMO.
One thing in particular I tend to like about the Steelers is that they develop and reward from within the organization. They never throw extremely large contracts at "big name" outside free agents, and history has shown that those deals rarely provide an equal value in return for the teams giving them out.
Cam is clearly the best young defensive player on the Steelers at this point in time. He has shown himself to be hard-working and plays with a relentless intensity. By accounts I have read, he is also considered a leader and is well-respected by his teammates. I see opposing O-lineman struggling against him consistently in games. He is not an average 3-4 defensive end in the least.
6 yrs/60 Million is a realistic fair deal for him IMO. Yes, you can't pay every player that type of deal, but you have to peg and sign guys as the central building blocks. Maurkice Pouncey got a large deal last offseason because he is clearly the leader on that Oline, has immense talent, brings it every play, etc. His deal was worth it, and I don't see anybody complaining a year later that it was an unwise signing.
My guess is that the Steelers will lose some good players along the way in the coming seasons just because they can't pay large money to everyone, but since the start of this century, I can't think of any large signing that turned out badly except for the Woodley contract and Jason Gildon (..if my memory of Gildon after he signed his big deal is correct.....it's possible I am wrong on this).
