Back in October, NFL Network reported that the Bills and Dick Jauron had reached an agreement on a contract extension that would run through 2011.

Neither Buffalo nor Jauron confirmed it, leading to questions in recent weeks about whether the deal ever got finalized.

But it did. No one wants to say when, and no one will say for how much, but this much is known: Much to the disappointment of Bills fans, the deal was signed and will last through the 2011 season, according to league sources.

So if Bills owner Ralph Wilson wants to change, he’s going to have to eat the contract he just handed over. Still, it’s not inconceivable that the Bills would turn their back on Jauron and fire him after this season. Jauron’s contract contains offset language that means Buffalo would have limited liability if its head coach found another coaching job elsewhere.

But Buffalo has made its financial commitment to Jauron, and as much as it might want to make a change, it’s going to be difficult to do it. For a small market, cash-strapped team that moved a home game against Miami to Toronto mostly for money, it’s unlikely the team would be willing to eat what’s left of Jauron’s new contract.
