Kirk Cousins stabilized the position, but Friday's preseason opponent, the New Orleans Saints, have needed only Drew Brees since trading for him in 2006.
If you want to know why the Vikings front office went out on a limb last season to sign Kirk Cousins to what was at the time the richest quarterback contract in NFL history, look no further than Saints QB Drew Brees, who the Vikings will briefly face Friday night in their first preseason game.
Since the Chargers traded Brees to New Orleans in 2006, he has started 205 of a possible 208 regular-season games and has a 125-80 record.
