Simply put Mike Williams has left a horrid taste in the mouths of Buffalo fans and staff.
Although cheaper and younger, drafted players are unproven on the NFL stage. Dockery, Walker, and Whittle know what it's like to push the big men, they know how to block for NFL calibur players, and they know the significance that this is, in fact, their form of income. Multiple millions of dollars? Not a small price to pay, but a price that is well worth the income this team can generate if they become a .500+ team with the upgrades.
Defense was targeted last year in the draft, and it will be this year too, unless a miracle trade pushes through.
God speed Marv.
