In the offseason, the Lions gave quarterback Matthew Stafford a fat new contract. As a result, they’re now stuck with him — no matter how poorly he plays in crunch time of key games.

On Monday night, Stafford threw a pair of fourth-quarter interceptions, dragging his passer rating in the final fifteen minutes of the last five games down to 29.5. Before last night, Stafford had a fourth-quarter passer rating of 30.2 in the prior four games.

Still, coach Jim Schwartz (who soon may not be coaching Stafford or any other members of the team) vouches for the first overall pick in the 2009 draft.

“I think he’s an accurate passer,” Schwartz told the media at his day-after press conference, via Dave Birkett of the Detroit Free Press. “Matt’s a very mechanically sound quarterback.”

Stafford wasn’t very accurate last night. And if by “mechanically sound” Schwartz means, “He has a release point ranging from John Unitas to Kent Tekulve and all points in between,” then Stafford is indeed mechanically sound.

Two days after Cowboys coach Jason Garrett called out Cowboys quarterback Tony Romo for calling an audible at the worst possible time, it’s actually good that Schwartz has Stafford’s back. Schwartz knows that, if the team is going to climb out of this funk and save Schwartz’s job, Stafford will be leading the way.
