See, the weird thing is that Steve Bono was really, really good.
In all likelihood at least.
For five long years, from 1989 to 1993, Bono was stuck as the Niners’ second- or third-string quarterback, condemned to the clipboard and baseball cap behind Joe Montana and Steve Young. In 1991, Bono started six games when the two aforementioned Hall of Famers went down with injuries; he went 5-1 as a starter en route to the fourth-best QB rating in the league (behind Young, Jim Kelly and Mark Rypien).
In 1994, Bono was traded to the Kansas City Chiefs, where he became the backup to … Joe Montana. Upon Joe’s retirement, Bono finally got his chance to be a starting quarterback in the NFL. He made the most of his long-awaited opportunity, leading the division-winning Chiefs to a 13-3 record and representing the AFC in the Pro Bowl.
Bono also played for the Vikings, Steelers, Packers, Rams and Panthers during his career. According to Wikipedia, he currently lives in Palo Alto and works at a San Francisco investment bank.
The greatest third-string QB ever?
