A few have suffered injuries costing them playing time. Some are aging veterans beyond their prime. Others are young studs flirting with one-season-wonder status. Some are sleepers that have yet to awake.

Whatever the classification, there are plenty of fantasy busts so far this season. Here’s a look:

QB — Daunte Culpepper (Dolphins): Drafted in the fifth or sixth round in most 10-team redraft leagues, Culpepper looked to be a high-value pick, assuming he at least approached striking distance of his early days in Minnesota. Not only hasn’t he come close, he’s been so abysmal, he’s been benched in favor of, gulp, Joey Harrington. Make no mistake, while coach Nick Saban claims it is an injury keeping Culpepper sidelined, if he had performed well, rather than stink up all of South Beach, the FT believes he would still be under center.

RB — LaMont Jordan (Raiders): A first-round pick in most leagues. Now he possibly lives on your waiver wire. His short-term and long-term outlooks quickly have become grim. The guy has been a draft-day killer.

RB — Shaun Alexander (Seahawks): Wasn’t exactly tearing it up before he went down, but that was better than missing the last four games (and the next one, at least). Brutal considering where he was picked in the draft.

WR — Chad Johnson (Bengals): Fantasy owners are missing the parade of end zone celebrations. He has only two TDs and exactly zero 100-yard games.

WR — Larry Fitzgerald (Cardinals): In some drafts, he went as high as early second round. Hasn’t played since Week 5 and has only two productive weeks so far for fantasy owners. When he returns, he will have a new QB and a new offensive coordinator.

TE — Jason Witten (Cowboys): Was on the outer fringes of the top-tier TEs entering the draft. It was believed he often would be the beneficiary of secondaries devoting too much manpower to covering Terrell Owens and Terry Glenn. Until last week vs. Carolina, if he was open, he wasn’t getting the ball. Tony Romo is a much less experienced QB than Drew Bledsoe. Less experienced QBs tend to rely more on the tight end, so expect Witten’s second half to be much better.

PK — Mike Vanderjagt (Cowboys): Pick an adjective: inconsistent, unreliable, untrustworthy, inaccurate, fallible, erratic, unstable, etc.

DEF — Indianapolis Colts: A top five defense taken, among the bottom five in fantasy rank.

QB — Carson Palmer (Bengals): Has been slow to get back to form following a knee injury. Much of the blame can go to his offensive line (already sacked 21 times, compared to 19 all of last year).

RB — Edgerrin James (Cardinals): Hard to keep him off the first All-Bust team. Edge is barely on pace to eclipse 1,000 yards, and his chances of reaching 10 TDs are looking very slim (he has only three).

RB — Cadillac Williams (Buccaneers): A late-first, early-second round selection in most leagues. Has one TD and is averaging less than 60 yards a game. Not sure he’s been penalized by the loss of QB Chris Simms. He was terrible before Simms went down. Like the Raiders, this is an offense in disarray.

WR — Chris Chambers (Dolphins): He was phenomenal to close out last season, and was expected to be the main beneficiary of the arrival of Culpepper. Well, we know how that turned out.

WR — Randy Moss (Raiders): It doesn’t help that he has some guy named Andrew Walter, who enjoys the same amount of fame as the guy who sang the chorus in Shannon’s 1980’s skating-rink hit “Let the Music Play.” He’s unhappy, unmotivated, surrounded by incompetence. And any shiny, happy feeling from two straight wins will meet with harsh reality when they are crushed this week in Seattle. Raiders could go 1-8 or 0-9 to close the season (maybe they beat the Texans, maybe).

TE — Heath Miller (Steelers): Since a huge Week 1, he’s been invisible. Take away his 85-yard TD in that game, and he’s been invisible all season.

PK — Jason Elam (Broncos): Taken among the top five kickers. Barely ranks in the top half.

DEF — Tampa Bay Buccaneers: One of the top five or seven defenses pick, one of the bottom five or seven in fantasy production.

QB — Kurt Warner (Cardinals): Had the best WR tandem in the league (before Fitzgerald was injured), an All-Pro RB, and now he has a spot reserved on the bench.

RB — Reggie Bush (Saints): In some drafts, he went as high as the second round (and likely first overall in keeper leagues). Still could be worth his keeper status, but needs a dramatic turnaround in recent production to give you a boost this season.

RB — Jamal Lewis (Ravens): There weren’t great expectations for the former 2,000-yard back, but some did expect some type of resurgence — enough to land him around the fifth round in most 10-team redrafts. He has one TD thus far, and one 100-yard game (which came last week).

WR — Marvin Harrison (Colts): Often one of the top five WRs taken, Harrison ranks a paltry 18th in basic scoring formats.

WR — Rod Smith (Broncos): Has yet to amass even 70 yards in a single outing (something he did eight times last year) and has scored only once. Ranked in the mid-20s among WRs on draft day, ranks 66th today.

TE — Jeremy Shockey (Giants): Many took Shock in the first five or six rounds. His high this year is six catches, and no 100-yard games (he had four last year).

PK — Sebastian Janikowski (Raiders): Hard to score as a kicker when you’re offense can’t move the ball.

DEF — Carolina Panthers: Second defense taken in many drafts, yet they rank near the bottom third of the league in fantasy production.

NOTE: I used as a reference for the All-Fantasy and All-Bust teams a great site called Average Draft at antsports.com. This site in an invaluable tool before draft day, allowing you to gauge an approximate draft position of target players. Try it out next season.
