Here's my two cents... take it for what it's worth.
To be a "Buy Low" opportunity, a player would have to have a few characteristics:
1) Must have some question marks heading into the season that make their expected performance hard to predict
2) Must have trends in the past to indicate that a poor performance may continue in the future.
3) Must have indications in the current situation that poor performance will continue in the future
4) Trades involved must have options to replace the "buy low" player.
Unless you're dealing with guppies, most vet's will know the value of their players. If I own Shaun Alexander, even after his performance, there is no way I move him (and say Rod Smith) for anything less than Steven Jackson and Chris Chambers. And those kind of deals are tough to make (on both sides). Now, if I'm a SA owner and I already have Jackson and someone like Willis McGahee, and I'm offered Terrell Ownes, then maybe I think about it... but normally teams are overloaded with top 20 RBs.
Here's my analysis of the players listed:
Quarterback
Marc Bulger - Yes, rams 1st team has been poor and Bulger is a middle-of-the-pack QB anyway.
Daunte Culpepper - Yes, injury last year and propensity to turn the ball over make his future quality questionable. He could go either way, but the Dolphins are a better team that the 05 vikes were.
Matt Hasselbeck - unlikely - he was projected to be a top 5 QB, and had an injured Jackson last week, and now adds Branch. His value would likely go up more than down.
Peyton Manning - Not a chance. Peyton was probably the first QB taken, and unless you're offering a top 5 QB AND something else, you're unlikely to get Peyton unless the owner is EXTREMLEY Pannicky...
Carson Palmer - See Peyton, except for the injury concern (which didn't display itself in week 1).
Jake Plummer - unlikely. Most know his poor week 1 history, and his team and passing options specifically have improved since 2005.
Running Back
Shaun Alexander - Again, top RBs wouldn't drop in value much. You MIGHT be able to pry Alexander away with an offer of Stephen Jackson and Chad Johnson, but it's unlikely someone would trade the person they thought would be one of the top 3 RBs in the league after one poor game.
LaMont Jordan - Possibly - stats were terrible, and the entire team stunk, but you may be able to move him for someone notched 5-10 places below on the opening projections
Jamal Lewis - Good one. Poor history last year, competition at the position, improved air attack could all affect him negativley.
Willis McGahee - Unlikely but possible.
Clinton Portis - Also possible. His shoulder injury could limit him for half a year or more if the injury is aggrivated, and some may not want to take that risk.
Wide Receiver
Isaac Bruce - Downward trend over the past 2 years plus Kevin Curtis make him risky, and a good buy low if you think his 10 targets/game will continue.
Antonio Bryant - Not sure how low you can get him... he's #1 in SF as was probably taken around WR#40. More than likely you'd have to offer something higher than his ADP to get him, which means you're not buying low.
Chris Chambers - Perhaps, although I've been waiting for Chambers to break out for about half a decade.
Michael Clayton - Good pick - doesn't have a great history, but could be solid this year after a ho-hum week1.
Braylon Edwards - Could be, but is risky with his QB and Winslow.
Lee Evans - Like Bryant, was probably not selected with a high pick.
Torry Holt - Unlikely as a Holt owner would have to see at least 4 concecutive weeks of poor performance before "giving up". Expect to trade someone like a Chris Chambers AND Fred Taylor to pick up Holt (i.e. a boarderline top-10 WR and a RB#3), which is not something that most owners would be willing to do.
Joe Horn - Good one - poor year last year, poor game 1, new QB, but should get better.
T.J. Houshmandzadeh- Perhaps out of sight out of mind....
Darrell Jackson - Like Holt, he was probably taken to contribute, although the injury is holding him back. Owners would likely want to see how he does "uninjured" before moving him.
Chad Johnson - See DJ above but remove the injury concerns.
Derrick Mason - I think people expect the renunion with McNair to be a good one, but the Ravens offensive plans may make some worry. Boarderline.
Randy Moss - See Holt
Steve Smith - You'd have to move a WR like Chad Johnson to get Smith (IMO)
Reggie Wayne - Possible
Troy Williamson - See Antonio Bryant.
Tight End
Todd Heap - Possible, people may have forgotten about the strong finish
Randy McMichael - Probably went arond the middle of the TEs drafted, and not sure he will peform much better than that, or any of a dozen TEs around him.
Jason Witten - a good one...
