Dan Fouts might disagree with this as well as Warren Moon.
The issue with Young is he sucked in Tampa and then was a backup for years and then got to play on a team that won 4 Super Bowls prior to him starting. As good as he was he was helped by a great surrounding cast/coaching staff. I mean outside of Young he had other HOFers around him like Rice, Bryant Young, Rickey Jackson and Deion Sanders.
