I have not decided whether I want the Bills to spend the money to sign Mathis, but I do know this:
1) Given the questions about our QBS, other teams are going to stack the box. As a result, if the Bills want to be able to run the ball, whoever is on the line better be able to open up some holes.
2) At the end of the day, the Bills better have enough money to extend Marcell, Gilmour, Nigel, and Cordy.
Just my two cents.
