Yes, Moon was a CFL star, but he was inducted due to his NFL accomplishments. Yes, Jim Kelly was a USFL star, but he was inducted due to his NFL accomplishments.
The Hall states both leagues accomplishments it does not distinguish. People in this thread can't get over this I guess.
You are technicall correct that the Hall mentions accomplishments in both leagues. But I think its a stretch to make the point that there is no distinguishing between the leagues. THe Hall mentions he went into the CFL where he won 5 Grey Cups. It goes into extreme detail about his NFL experience. Nine Probowls. Nine 3,000 yard seasons. etc.
If you think the mention of the CFL accomplishments was because it was significant, I think you are mistaken.
From the Hall of Fame website:
"Harold Warren Moon . . .Began pro career with CFL’s Edmonton Eskimos, winning five straight Grey Cups. . . Signed with NFL’s Houston Oilers, 1984... Completed 3,988 of 6,823 passes for 49,325 yards, 291 touchdowns, 233 interceptions in 17-season NFL carer. . .Nine 3,000-yard passing seasons was third in league history. . .Named to nine Pro Bowls. . .Had four 4,000-yard passing seasons. All-Pro, 1990…First or second team All-AFC 1988, 1989, 1990…Born November 18, 1956 in Los Angeles, California. "
I guess you could argue that The Hall mentions he was born in Los Angeles in 1956 and played in the NFL. It does not distinguish between the two. So were they equally important in deciding to induct him??
