With his winningest season, Kirk Cousins saved the Minnesota Vikings, however temporarily, from the most perilous process in American sport:
Finding and developing a transformative starting quarterback.
The Philadelphia Eagles have built one of the best rosters in the NFL, but if they hadn't spent a late second-round draft pick on a running quarterback who transferred in college because he lost his starting job, they would not be in the Super Bowl today.
Jalen Hurts is the Eagles' leader and most important player. He's one of the five most valuable players in the league. When the Eagles selected him in 2020, they raised more eyebrows than expectations.
That's how inscrutable the quarterback evaluation process is.
This plan led to a Super Bowl, and this plan didn't go as planned.
In 2016, the Eagles used the second pick in the draft on North Dakota State quarterback Carson Wentz. He became an MVP candidate in 2017, leading the Eagles to an 11-2 record before injuring his knee.
The Eagles would win the Super Bowl that season, in Minneapolis, with journeyman backup quarterback Nick Foles.
