In a recent article on Bleacher Report by Kristopher Knox, the Buffalo Bills and Minnesota Vikings smartest move this offseason was the same, which was the trade of Stefon Diggs. This could end up being a case of a win-win trade, which is not always the case in the NFL.
For the Buffalo Bills, Knox wrote about the trade from their perspective:
The Buffalo Bills’ addition of wide receiver Stefon Diggs wasn’t a thrifty move as some on this list were. Acquiring him cost 2020 first-round, fifth-round and sixth-round picks and a 2021 fourth-round pick—Buffalo got a 2020 seventh-rounder in return.
