For the second time in as many years, the Vikings are dealing with the ultimate injury broadside in all of professional sports: losing their starting QB. No position is more important, and typically the drop-off in performance between starter and backup is steep, unless your starter sucked to begin with.
Entering the regular season, the Vikings were about as deep at QB as anytime I can remember. Beyond Bradford as starter, Case Keenum was the primary backup, who looked good in extensive time in pre-season. Keenum looked like an improvement over Shaun Hill as well- younger, stronger arm, better mobility- and yet also with a fair amount of NFL starting experience.
