Warren Moon last played for the Oilers in 1993. In 1994, Billy Joe Tolliver, Bucky Richardson and Cody Carlson split QB duties for Houston. In 1995, while Steve McNair was on the roster and did play in 4 games, Chris Chandler was the Oilers QB. Chandler was the man again in 1996, outplaying McNair 12 games to 9. McNair didn't play a full season until 1997. Hardly what you'd call Warren Moon's successor.
And Plunkett did not replace Ken Stabler. After the 1979 season, the Raiders traded Stabler to the Oilers for Dan Pastorini. Pastorini started the first 5 games, but struggled and then got injured. The Raiders resorted to Plunkett, who was on the squad merely as a back-up.
Marino was not the successor to Griese. David Woodley was. Griese retired after the 1979 season. Woodley started for 3 years. Then, in 1983, the Dolphins began using their rookie Marino. I think it would be hard for Griese to pass the torch to a senior in high school 1100 miles away.
The three comments above mine are very accurate! Well, I still had fun with the quiz and I scored 13/14. I forgot that Trent Green had played with the Rams. Thanks for the quiz!
