One of the greatest of his time, if not all time. Also a proud American hero. Unfortunately, people hate him for being 'bitter' towards today's players, which I think wrongly colors his wonderful career. Hopefully, he'll be remembered alongside the likes of Seaver, Johnson, Ryan, Koufax, and others as among the most dominant pitchers in MLB history.
I remember as a kid, seeing the USS Alabama which he serves on during the war, and they had his bunk marked and a little plaque dedicated to him. I had never heard of him really so I found a book in the library that told an abridged tale of his life. Seemed like a great man.
