Here's an incomplete list of quarterbacks the Vikings should have beaten but didn't:
1990: Bob Gagliano. '91: Hugh Millen. '92: Rodney Peete (not a terrible quarterback, but this started a streak of losing to Peete in three straight seasons, which shouldn't happen to a playoff contender). '93: John Friesz, Craig Erickson and former Viking Wade Wilson. '94: Erickson and former Cretin-Derham Hall star Steve Walsh, who beat them 35-18 in the playoffs.
1995: Erik Kramer, Trent Dilfer and Jeff Blake (they lost twice to Kramer in '95, and would lose to Dilfer in four straight seasons). '96: This is an all-timer: Dave Brown, Steve Bono and Friesz. '97: Dilfer again. '98: The Vikings would go 15-1, 16-2 including playoffs. Their losses were to two non-Hall of Famers — Dilfer and Chris Chandler. '99: Shane Matthews, future Viking Gus Frerotte and Shaun King.
2000: King. '01: St. Paul native Chris Weinke, Jim Miller (twice), Aaron Brooks, Kordell Stewart, Mike McMahon. '02: Miller, Peete, Dilfer, Chad Pennington. '03: Doug Flutie, Rick Mirer, Marc Bulger and, infamously, Josh McCown. '04: Chad Hutchinson, Patrick Ramsey.
2005: Brian Griese, Kyle Orton and Kyle Boller. '06: J.P. Losman, Joey Harrington (at Miami), Pennington. '07: Damon Huard, Todd Collins. '08: Orton and Jeff Garcia. '09: Matt Moore.
2010: Chad Henne, future Viking Shaun Hill. '11: Another all-timer: Future Vikings Josh Freeman and Matt Cassel, Tim Tebow, McCown again. '13: Brian Hoyer, a tie with Scott Tolzien and Matt Flynn, another loss to Freeman. '17: Does backup quarterback Nick Foles in the playoffs count? Probably not. '18: Mitch Trubisky (twice). '19: Chase Daniel, Moore.
