3. Warren Moon
Warren Moon played in the Canadian Football League from 1978-1983, after going undrafted in the 1978 NFL Draft. He won five Grey Cup championships — their equivalent of the Super Bowl — as the starting quarterback of the Edmonton Eskimos. But, i’m guessing he’d happily trade any one (or more) of those Grey Cup titles for just one Super Bowl ring. When the Houston Oilers were finally wise enough to bring Moon back to the U.S., he became one of the most prolific passers of the late 1980’s and early 1990’s. Moon led the league in passing in 1990 and 1991, recording over 4,600 passing yards in both of those seasons. No player had put up those types of passing yards in back-to-back seasons in NFL history to date. But, while the Oilers made the playoffs seven straight years between 1987 and 1993, with Moon at the helm, they — and Moon — never got further than the AFC divisional playoffs.
