Eja, try using single seasons. Who cares what other people will "let" you have, lol. Constructing the roster using single-seasons is a valid way to do an all-time team. It's just a different type of all-time team. Go for it. That way you get to have a truly sick roster. Like I mentioned, you get a CB duo of Haynes (pick any of his All-Pro seasons for the Pats) and Revis (pick last year). You get HOFer Curtis Martin as a Pro Bowl rookie for RB. Way more freedom, way more fun, way better roster.
