If you’ve been fortunate this season, you’re most likely poring over tough lineup decisions this week that will affect your fantasy football playoff positioning. The rest of you are likely mailing in a team that has no chance at all at making the postseason.

Those of you in the latter category probably have run across a team killer or two, those guys who were top choices on everybody’s draft boards but have instead performed at mediocre levels or worse.

I know it’s the holiday season, and we’re all supposed to be forgiving, but I don’t think you’d find too many fantasy owners wishing glad tidings to these prime offenders. Here is a lineup that would have seemed like a championship team at season’s start, but reality had other cruel ideas. Please save your lack of applause until all players are announced.

QB Brett Favre, Minnesota: Hopefully, you jumped off this train wreck early on. If, fooled by the Randy Moss acquisition, you held out hope after the rocky start, you’ve been rewarded with three games with at least three interceptions as opposed to one with three touchdown.

All of this comes off a 33 touchdown season which made Favre a hot fantasy commodity once again

RB Ronnie Brown, Miami: One of the most consistently overrated players in fantasy history, the bottom finally dropped out for Brown this year. His supporters have constantly cited his health as the reason he’s never truly busted out.

Well, he’s been healthy this season, and he’s produced three TDs and not a single 100-yard game.

RB Ryan Mathews, San Diego: At one of my drafts this year, I had a choice between Rashard Mendenhall and Mathews for my second pick, and I remember really having a tough time deciding before settling on Mendenhall.

Talk about dodging a bullet. Yes, Mathews has had some injuries, but he wasn’t productive even when he was on the field.

RB DeAngelo Williams, Carolina: An injury ended his season after six games, but that was probably a relief for his owners. Coming off back-to-back impressive seasons, Williams went in the top two rounds of just about every draft. He was averaging a punchless 60 yards per game this season when he got hurt, with one measly touchdown.

WR Randy Moss, Tennessee: It may be hard to fathom now, but Moss was generally one of the top three receivers chosen this year, usually gone by the second round. And he did have three touchdowns in the first three games for New England, along with a couple for the Vikes. But anybody keeping a glimmer of hope has been seriously burned by his flameout with the Titans.

WR Larry Fitzgerald, Arizona: I know that he’s been victimized by the horrendous quarterback play in Arizona, but there were some warning signs showing up last season that Fitz might be in decline. Even with Kurt Warner throwing, he averaged just 11.3 yards-per-catch in 2009. The burst that he showed during the Super Bowl run of two years ago has been seriously missing.

TE Brett Celek, Philadelphia: The tight end position as a whole has been a problem area for fantasy owners, what with key injuries (Jermichael Finley, Dallas Clark) and slumps (Visanthe Shiancoe, Zach Miller, and many more.)

But Celek, coming off a monster 2009, has never gotten in synch with Michael Vick, and that’s been seriously troubling for his owners.
