Risers:
QUARTERBACK
Tim Tebow - DEN: Just when we thought Tebow had hit the wall and was going to eventually be pulled for Brady Quinn, he managed to salvage his career by putting up 242 yards from scrimmage and two passing touchdowns. He still absolutely blows as a passer, only hitting 46.4 of his passes. But as long as he can keep those running yards going and the scores, owners can continue to use him as a QB2 in two-quarterback leagues and as a flex option.
RUNNING BACK
Chris Johnson - TEN: Johnson was finally able to find space on the outside against the Bengals, which allowed him to put up one of his better statistical games since Week 4 (110 total yards). Mike Munchak revealed that the team ran the same plays they had in previous weeks, so hopefully this means the light finally went off in Johnson's head. He'll take the momentum into Week 10 against a soft Panthers Defense that is giving up 133.2 rushing yards a game along with 11 rushing touchdowns.
WIDE RECEIVER
Julio Jones - ATL: Jones didn't miss a beat after missing two games with a hamstring injury. He notched his third 100-yard game of the season and scored his first and second receiving touchdowns of the year in the blowout win against the Colts. Jones should be heavily involved in the first divisional matchup against the Saints in Week 10.
TIGHT END
Brent Celek - PHI: The Eagles winning streak may have come to a screeching halt against the Bears Monday night, but Celek continues to climb as a fantasy option. Over the last three weeks, Celek has racked up 18 receptions, averaged 65.3 receiving yards and scored twice. With a strong matchup against the Cardinals, Celek could be a sneaky option to plug in for Week 10.
Fallers:
QUARTERBACK
Colt McCoy - CLE: McCoy hasn't been the worst quarterback in the league, but he's been very inconsistent over the last two weeks. Against Seattle, San Francisco and Houston, McCoy has managed a meager 2 touchdowns to 3 interceptions and is coming off a horrific loss to the Texans. McCoy was never going to be a bonafide starting fantasy option, but he is turning into a weak No. 2. There are talks that Mike Holmgren may look elsewhere for the team's franchise quarterback.
RUNNING BACK
Joseph Addai - IND: I can easily name about 80% of the Colts offense in this list, but Addai takes the cake. Not only has he been a dismal fantasy option this year, but he is no longer part of the team's week-to-week game-plan. He was the emergency running back last week and is expected to play the part in Week 10 against the Jaguars. Addai's hamstring is partly to blame, but he has been on the sidelines and suited up. This running game is reeling from the loss of Peyton Manning.
WIDE RECEIVER
Johnny Knox - CHI: Many experts consider Knox the best receiver on the Bears' offense, but the coaching staff isn't giving him much of a chance to show anything on the field. Knox is coming off a one-catch game against the Eagles and has yet to catch more than 3 passes since Week 3 against the Packers. If you have Knox, hoping he finally has that breakout game, you can drop him because it ain't coming.
TIGHT END
Vernon Davis - SF: The 49ers are looking good, but fantasy owners can't be happy with what they are getting out of Davis. Unfortunately, because Davis is one of the better blocking tight ends, he has been asked to pass protect more than he has been asked to run routes. He's averaging a mere 42.4, but it's a bit skewed because of his 114 receiving yards against the Bengals back in Week 3. Currently on a 6-game winning streak, there is no reason for the coaches to change Davis' role going into Week 10.
