Three reasons why the Bills likely preferred Miller to Mack…
1. Mack coming off injury vs Miller having 4 sacks in the playoffs.
2. Mack required draft capital 2nd and 6th, Miller required no picks (but will impact the comp pick formula).
3. While all details aren’t out on the Miller contract yet, the Mack Cap Hit moves to 23M for years 2 and 3 with the Chargers and no additional years to spread it out if needed. Miller’s deal likely has a lower cap hit and more flexibility.
