Suh has actually been a very good player the last few years. He was hardly the reason the Miami defense struggled, and I have no idea why Gase got rid of him. He was the best player on that unit in 2016, his last year there, although Wake had a good season too. He also mostly dominated the o-linemen facing him in the playoffs this past season.
Not sure what games folks are watching with regard to Suh. When he faced off against the Bills while in Miami, he was rag-dolling the man across from him regularly.
