I think Troy, Harrison, Taylor and Keisel (has one year left I believe) were done regardless. Loved everything they brought to the team, but the Steelers need to return to getting rid of guys a year too soon rather than a year too late.
I don't see what Worilds would bring to the team besides a veteran presence. Not a dynamic pass rusher or run stopper and does not doing anything impressive in coverage. He is a guy who adds to his numbers with unblocked sacks.
McCain and Blake are two valuable depth players who are cheap and can play in a pinch. A nice duo for the No. 4 and 5 spots.
The Steelers need to break from Allen at some point, but he is good enough in a backup role that he sticks around for at least one more season. Knowing how this team operates, he may even start over Shamarko.
Will Allen
