Harrison twice played hardball with the Steelers to get what he wanted. First time, the Steelers said no and simply released when he wouldn't agree to a salary reduction. The second time, they gave him what he wanted and allowed him to walk.
Do I like it? No. I don't like how he handled it (although I am thankful he didn't take it all over the media like some other Einstein Steelers we could mention), and I don't like how he later sniped at Steelers Nation that supported him all these years.
That being said, he didn't pull this crap in the midst of his body of work. The first time it was pure business and nothing much was said outside of that. The second time it was after his body of work had been completed for the Steelers. There is no way that should reflect on the years of unbelievable plays this guy has made in the black and gold. That being said, it's probably a little too soon to have this discussion because as someone else said, the wounds are still a little fresh.
