After playing in only three games in 1984, Steve Grogan was right on the cusp of fulfilling many critics' expectations and officially being washed up. Lots of people thought little of his ability anyway, and his playing through many injuries over the years when he shouldn't have hurt his body and his statistical record.
But, he remained ready, and when Eason went down in 1985, he shook off the rust and utilized his experience and competitiveness as well as any older quarterback ever has. Berry deserves credit for letting Steve call his own plays, but he absolutely and obviously should have started him in Super Bowl XX, and again in Denver a year later.
"People think I'm old and beat up, so I can catch them off guard a little bit," he said during the win streak in 1985. He played like a champion.
Cam Newton has this type of opportunity today, whether he starts at first or not. The Patriots are still a team, not dependent on stars, although Edelman qualifies.
