It's shaping up to be a bad year to be an NFL offensive coordinator.
Three of them got canned during the preseason and a few more pink slips could be handed out in the near future.
Raiders passing game coordinator Ted Tollner can't feel too secure about his job when his team doesn't average even half the yards that the Saints gain per game.
Below, we take a look at the worst offenses in the NFL through six weeks.
Oakland Raiders (213.8 yards per game)
Could Raiders quarterback JaMarcus Russell possibly be getting worse? The numbers suggest he is.
Oakland is averaging a pathetic 125.3 yards per game through the air this season, nearly 23 yards less per game than last season when the Raiders also led the league in passing ineptitude.
Russell is the only starting QB in the league not to have completed at least half his passes (46.4 percent). As if those numbers aren't bad enough, the 2007 first-overall draft pick has also tossed six picks and lost four fumbles in six games.
While Russell and the Raiders “exploded” for 224 yards and a touchdown in their 13-9 upset of the Eagles Sunday, more than a third of that yardage came on an 86-yard TD catch by tight end Zach Miller.
The under has cashed in four of Oakland's six contests and the Raiders are 3-3 against the spread.
Cleveland Browns (239.8)
Being on this list is nothing new to the Browns, who ranked second-last in total offense last year as well.
An anemic passing attack has once again been the culprit in Cleveland. Opening-day starting QB Brady Quinn lost his job after posting a 62.9 QB rating in the first three games. Derek Anderson has been even worse, compiling a 41.7 QB rating.
The Cleveland pivots didn't get any help when the Browns traded big-play receiver Braylon Edwards to the Jets earlier this month. In the Browns' only victory so far, a 6-3 barnburner at Buffalo Oct. 11, the team completed only two passes to tie the NFL record for fewest completions by a winning team.
Under bettors haven't been able to cash in on Cleveland's offensive woes, going 3-3. The Browns have won their last three against the spread after dropping their first three.
Kansas City Chiefs (259.2)
Cassel, in his first season with the Chiefs after filling in for Tom Brady last year, has completed 57.4 percent of his passes and thrown seven TDs to only two interceptions. Still, Kansas City is averaging less than 162 yards a game through the air and is last in the league in third-down conversion rate (21.4 per cent).
The Chiefs haven't got much from their running game, either. Larry Johnson is a shadow of his former self, averaging 2.7 yards per carry and failing to reach the end zone through six games.
Kansas City's struggles on the other side of the ball (29th in total defense) have caused the Chiefs to go 3-2-1 over/under.
They have covered their past two contests, including an upset win in Washington last weekend, after losing the cash in their first four games.
San Francisco 49ers (267)
The days of Bill Walsh, Joe Montana, Steve Young and Jerry Rice are a distant memory in San Fran.
The current Niners offense features unspectacular QB Shaun Hill and a little-known receiving corps other than the long-past-his-prime Isaac Bruce. Tight end Vernon Davis is San Fran's leading pass catcher, hauling in 22 balls for 262 yards and three touchdowns in five games.
Coach Mike Singletary's preference to run the ball took a hit when star running back Frank Gore was injured in Week 3. Gore, who averaged 6.2 yards a carry and scored three touchdowns in his first three games, might return from his ankle injury this weekend against the Texans.
Despite its offensive impotence, San Fran has covered four of five games, including all three with Gore in the lineup. The Niners are 2-3 over/ under.
Tampa Bay Buccaneers (277.7)
With Chucky no longer patrolling the Tampa Bay sidelines, the new horror at Raymond James Stadium is the Bucs' offense.
Byron Leftwich lost the starting QB job after Tampa Bay was shut out 24-0 by the Giants at home in Week 3. Josh Johnson replaced Leftwich under center and has thrown five interceptions in three-plus games.
The ground game has struggled as well, averaging less than 100 yards a contest.
Tampa Bay has gone over the total in four of its six games, but that hasn't been because of its offense. The Bucs defense has allowed 30-plus points three times already. Tampa is 1-5 against the spread.
