They build big buildings off the money lost by foolish bettors. You can get a line on anything....simply because someone is willing to risk money over it, no matter how unlikely a win. There's a line on the Jets, Raiders, Browns, Giants...etc, winning the SB. The concept is obviously absurd, but books put it out there to take sucker money.
If the Bills win or make the SB, I agree that Brady is gone. If they keep limping along Offensively, it would be a difficult sell---even to a team as poorly run as the Titians. Can we agree on that?
A very good line doesn't have bad games against bad run Defenses.
