Set: Quarterback, running back, defensive interior line, offensive tackle The Bills not only have Josh Allen locked in as a starter but they also have Jake Fromm under contract until 2024 and just signed Mitchell Trubisky . They may need to shed QBs, not add them. They also drafted Devin Singletary and Zack Moss in back to back years so they have them under contract until 2023 and 2024 respectively as well as signing Matt Breida and having Taiwan Jones , Antonio Williams, and Christian Wade signed. As fun as new running backs may be (and some people are suggesting the Bills go back to the well here), they simply don’t need it - especially considering the running ability of their quarterback.
