Got this off ESPN, on Favre:
1992: Brett Favre gets the first start of his career against the Pittsburgh Steelers. He finishes his first season as a starter with solid numbers -- 18 touchdowns and an 85.3 passer rating -- but also 13 interceptions and six fumbles.
1993: Favre regresses noticeably in his second year, throwing 19 touchdowns and an NFL-worst 24 interceptions with eight fumbles. Favre's poor play sabotages a talented Green Bay team, which includes Reggie White, and the Packers finish 9-7 and lose to the Cowboys in the playoffs & behind two more Favre interceptions.
Not saying Favre is the great QB ever, but if Henne ends up a similar player, i think we would all be happy! (only that he retires a few years earlier then Favre)
