No way. The guy has had a great career, but he's not even top 5 of all time, possibly not even top 10. I like him (although this shit is starting to annoy me), but you can not call him the greatest ever when he's blown the season for his team twice in the playoffs with INT's and has thrown more picks in his career than any other QB in history. He's too careless with the football and he costs his team some games because of it. A QB like that can never be considered the best of all time IMO.
Not sure why most have Marino near the top since he thru big pics in nig games himself. Not only that, he would blame everyone else around him when it happened. Marini is not in my top 10, Farve is in top 5 IMO
