I've always laughed at the fantasy owners who complain about bye weeks. It's as if no other team is suffering through them as well - only their team is decimated.

I think bye week complainers are the same people who whine about airport security, or criticize the world for the existence of Mondays because "Mondays suck." Meanwhile, we're all taking off our shoes before we hop on an airplane and, whether you want to believe it or not, we all experience Mondays. All of us.

I'm sure people who hate bye weeks like Nickelback, too.

The fact is, we're all going through this difficult time in the fantasy football season. And to be honest, I like it. This is my favorite time of year. It's when fantasy owners start showing off their depth, and it's when lineup decisions become even more crucial.

That means these start/sit columns are even more important. Here's to not screwing up your team in Week 4.

Quarterback

Start Ben Roethlisberger - The Steeler offense really got things moving against Carolina on Sunday night, and ESPN.com leagues. Considering his TE26 status, it doesn't make a whole lot of sense.

Among the 27 tight ends with 10 or more targets this year, Witten ranks 20th in Reception NEP per target. There are eight players ahead of him within the efficiency metric who can be found on many league waiver wires, including Travis Kelce and Owen Daniels.

Witten is getting enough volume, but he's not doing enough with it. His matchup isn't terrible this week, but it's generally difficult to trust a guy who's been so inefficient to start the year.

Start Owen Daniels - The season-ending hip injury to Dennis Pitta is sad news, but the show must go on. And fortunately for fantasy owners and the Baltimore Ravens, things could be worse.

Owen Daniels was always a borderline TE1 in Houston, and he'll now be gobbling up a lot of the tight end looks in Baltimore with Pitta out of the picture. Through three games - including a pass-heavy Week 1 where quarterback Joe Flacco threw the ball 62 times - Pitta saw 22 targets to Daniels' 11.

Daniels has been solid so far this year, ranking fifth out of the 19 tight ends with 10 or more catches in Reception NEP per target. Much of that has to do with the fact that Daniels has caught 10 of 11 passes thrown his way.

Daniels was able to produce TE1 numbers against Pittsburgh in Week 2, and with an increased workload, he's not a terrible option against Carolina this week. The matchup could be better, but Daniels should see volume.

Start Garrett Graham - I'm thinking positively here, so rather than giving you another sit, I figured I'd add another tight end streamer to the list this week. Don't overlook Garrett Graham, who caught five passes last week in a game that finally wasn't in Houston's favor - the team had to throw the ball a little more.

Though the Texans are three-point favorites against Buffalo this week, the Bills are a middle-of-the-road team at defending tight ends, allowing an average of seven receptions to the position in each game this year. Graham, in a tight-end friendly offense, could be a good guy to add given the injuries to the position this week.

Other Players to Start: Travis Kelce, Niles Paul
Other Players to Sit: Charles Clay, Coby Fleener

Defense

Start the San Diego Chargers - In Week 1, the Eagles sacked Jaguars' quarterback Chad Henne three times, recovered a fumble and scored a defensive touchdown. In Week 2, the Redskins sacked Henne 10 times, picked him off once and scored 18 fantasy points. And last week, the Colts had four sacks against the Jags to go along with three forced turnovers and a touchdown.

Sensing a theme? No matter how good or bad a defense is, you start them against the Jaguars. That's San Diego this week.

Sit the San Francisco 49ers - The 49ers defense hasn't been as strong as year's past, and now ranks 24th according to our schedule-adjusted metrics. Meanwhile, their Week 4 opponent, Philadelphia, has put together the seventh-best offense in the league thus far. With an over/under that's greater than 50, there's no reason to roll with the 49ers defense in your fantasy lineup this week.

Other Defenses to Start: Detroit, Pittsburgh
Other Defenses to Sit: Tampa Bay, Philadelphia
