Maybe they tried and couldn’t work it out. Remember, it takes two hands to clap.
the Bills are tight under the Salary cap. They have aging players such as Jones, Johnson, Milano with large salaries and cap hits.
they have young guns such as Hoecht, Oliver on IR and cannot contribute and yet their salaries count against the cap
them they have players who they paid big bucks but not delivered like Samuel, Knox, Bernard, White, Shakir, Palmer
and finally, their cost control players such as Davis, Williams, Coleman , Bishop (KC game could turn his career) have not stepped and contributed significantly.
The Bills can partake their draft picks but without offloading salary they cannot really make big decisions
