Week 11 Start 'Em, Sit 'Em: Sit Philip Rivers Against Rolling Bears Defense

The NFL can be a funny place, where great quarterbacks can go bad and mediocre quarterbacks can look like stars.

As in the NFL, fantasy football is all about playing the matchups and keeping track of how opposing defenses are ebbing and flowing.

That's not more evident than in Week 11's Start 'Em, Sit 'Em.

Start 'Em: Mark Sanchez, QB, New York Jets

I don't believe in Sanchez as an NFL quarterback as much as you all do, but that doesn't mean he can't be a good fantasy quarterback (i.e. Tim Tebow).

In Week 10 against the New England Patriots, Sanchez struggled, completing just 51 percent of his passes and tossing two interceptions.

Regardless, Sanchez still posted 21 points with 306 yards passing and two total touchdowns.

In Week 11, Sanchez faces the Denver Broncos, who are giving up the most fantasy points to quarterbacks this season.

Forget the fact that Sanchez hasn't proven to be a true franchise QB. Roll with him in Week 11 and you'll be just fine.

Sit 'Em: Philip Rivers, QB, San Diego Chargers

What has happened to the Philip Rivers we had come to know all these years?

Considered a great quarterback, Rivers has been a dud this season. After his 15th pick of the season on Sunday against the Oakland Raiders, Rivers has already equaled his career-high in that category and leads the league in interceptions.

Rivers faces a Chicago Bears defense that has been on a roll this season—at Soldier Field.

The last three weeks, the Bears have forced a whopping nine interceptions and held each quarterback to under 57 percent passing.

Rivers is already struggling. Throwing him into Soldier Field won't be pretty.
