Running Back
The one position that is probably the most pressing has to be running back. The team has Devin Singletary, who looks to be a breakout star, veteran T.J. Yeldon, the fan favorite Christian Wade, and the recently signed Taiwan Jones, according to Aaron Wilson of the Houston Chronicle.
The concern is that Singletary is still young, Yeldon has never really shown he can be a featured back if the need arises, Wade is very unproven and Jones was added primarily for his play on special teams.
This position has the look of being deep but that changes rapidly if Singletary is forced to miss an extended period of time. That is why the Buffalo Bills must look to add another running back, either in free agency or with their top pick in the second round.
While Josh Allen has the shiny new weapon in Stefon Diggs, his best friend in 2020 would be a strong running game. This is the reason it is important to get another running back that can compliment Singletary, but also step up if the need arises.
