The Fantasy Stock Watch tracks the most added and most dropped players in fantasy football after the first week of action, based on NFL.com users.
Most added: Devery Henderson
Henderson had six receptions for 100 yards and a touchdown in the Saints' loss to the Packers. Henderson is the NFL.com Saints receiver of choice with injuries to Lance Moore and Marques Colston thinning the pool.
Most dropped: Danny Amendola
Many had viewed Amendola as "Wes Welker-lite" in Josh McDaniels' offense. But a gruesome elbow injury has Amendola's status in doubt. However, be careful about pulling the trigger too quickly, because he has not been added to the IR just yet.
Stock rising: Cam Newton
More than 80,000 NFL.com fantasy users were quick to add Newton after his record-breaking debut against the Cardinals. How many of those people will end up releasing him if he struggles against the Packers in Week 2?
Stock falling: Peyton Manning
Many fantasy enthusiasts are doing the seemingly unthinkable and putting Manning on waivers. And with so many great quarterback options out there, releasing Manning in understandable. But are the people hanging on to him doing it more for nostalgia?
Stock rising: Cadillac Williams
Fantasy owners with Steven Jackson should certainly add Williams, who showed that he can still carry the load. Is he a great option for the entire season? Of course not. But if you need a short-term fix, or would like to carry some fantasy insurance, Williams is a great add.
Stock falling: Austin Collie
The injuries and presence of Kerry Collins is enough to sour any fantasy owner on the once-promising Colts receiver. Just missing this list is Pierre Garcon, clearly indicating that the Colts' peripheral receivers have fallen out of favor. Reggie Wayne still remains a great start.
Stock rising: Early Doucet
The Cardinals' preseason playbook seemingly consisted of one play - throwing it deep to Larry Fitzgerald. However, Doucet was the one who found himself the beneficiary of a heave from Kevin Kolb. But realize Doucet was only targeted three times in Week 1, so keep him on the bench.
Stock falling: Mike Sims-Walker
I really hope that people are not giving up on Sims-Walker too early, especially with a great matchup against the Giants in Week 2. With Amendola out, Sims-Walker should be on the other side of the ledger, but NFL.com users disagree.
Stock rising: Scott Chandler
Fantasy enthusiasts are targeting the big Bills tight end after he torched the Chiefs. The potential is there, but a guy like Benjamin Watson (available in more than 70 percent of leagues) is a better play.
Stock falling: Marques Colston
The broken collar bone could last well into the later weeks, so fantasy enthusiasts are making room, apparently by going for Henderson. That looks like the best move in the short term.
