In this article KFFL breaks down fantasy football busts of the week. Some high-level players will be included, because you need to know when is time to sit a player even though it may not seem appropriate. Primarily, however, we will address the midrange to low-end fantasy options that you rack your brain over each week. Read on to learn which of these players that you wouldn't want in your lineup.

Fantasy football busts: Defensive teams

San Diego Chargers vs. Jacksonville Jaguars

Fantasy value: Bench

• Despite being burned chiefly by big plays, the Chargers had a rough time during a rain-soaked Monday night loss to the Kansas City Chiefs, recording just one sack and failing to induce a turnover. San Diego will be back home in likely sunny conditions for Week 2, but they're still having trouble generating a pass rush, which is taking the jolt out of the Bolts' defense's ability to generate fantasy points.
• Though David Garrard takes plenty of sacks, Jacksonville's offense typically plays things close to the vest and was able to hold off another pass rush-deficient team last week (Denver Broncos). Expect them to do the same this week with running back Maurice Jones-Drew and the positive Jags' O-line, who should test the Chargers' weak run D. The Chargers probably will perform slightly better in leagues that reward your defense if they don't allow many points.
• If they're without linebacker Shawne Merriman (Achilles') once again, the Chargers would still have a debilitated pass rush. Even if he were to play, how close to game shape will he be in?

NEW - Chicago Bears at Dallas Cowboys

Fantasy value: Midrange No. 1

• The Bears' defense recorded two sacks, picked off a pass and recovered two fumbles in Week 1 against a Detroit Lions' offense that was missing Matthew Stafford (shoulder) for most of the contest.
• Even with their poor showing against the Washington Redskins, Dallas still racked up 380 net yards. They only surrendered one sack and quarterback Tony Romo didn't throw any picks. The Cowboys typically weren't a great turnover matchup for fantasy defenses last year, either.
• Dallas offensive linemen Marc Colombo (knee) and Kyle Kosier (knee) will both play this week, though they might be somewhat limited. They are both significant upgrades over Alex Barron and Montrae Holland.
