In the NFL, people talk about “duos” a lot, even when they don’t realize they’re doing it. Typically it seems most like the focus is either on the individuals or the teams — Is Antonio Brown the best receiver? Are the Patriots the best team? Who are the top five quarterbacks? But then again, so much simply comes down to pairs.
The top pair of pass rushers is better than the single best pass rusher.
The top pair of receivers is going to be a bigger threat than the single best receiver and the quarterback is going to benefit more from having a great duo.
