The Buffalo Bills, not the Minnesota Vikings, reached a conference championship in 2020. The connective link between the two franchises is Stefon Diggs, a player traded by Minnesota to Buffalo in 2020 for [what turned out to be] Justin Jefferson, Kenny Willekes, and three 2021 draft picks.
Diggs was terrific during his first year in Buffalo. This was no surprise as Diggs also played tremendously in Minnesota – he just received more offensive attention with the Bills. Indeed, Diggs led the NFL in targets, receptions, and receiving yards — a wide receiver’s fantasy.
The foreseeable future will dictate the “who won the trade” dialogue, but this cannot be adjudicated in good faith for several years.
