Andy Dalton, QB, Cincinnati Bengals. If you lost Romo or Brees and Dalton is available, snag him (Tyrod Taylor is my go-to guy here, but you already know I love him). Dalton is showing some nice progress in Hue Jackson's offense, and while the Ravens defense has been surprisingly strong this season, Dalton could put up good numbers moving forward. He's worth a grab on most teams. Just keep in mind that the Bengals do have multiple prime time games this season, and you may want to sit Dalton in them given Cincinnati's history in that setting. This week though, Dalton is your guy.
Ryan Fitzpatrick, QB, NY Jets. Fitzpatrick may be a bit of a reach, but he has looked solid so far this season, and the Jets have said that he would remain the starter when Geno Smith returns from injury. If you need an option at quarterback and Dalton and Tyrod Taylor aren't available, Fitzpatrick may be your guy.
Matt Jones, RB, Washington Redskins. Jones had a breakout game in week two, looking far more effective than Alfred Morris out of the backfield. While Morris remains the number 1 RB in Washington, Jones could be a sneaky good flex play this week. If nothing else, he's worth a stash and grab this week if he's not on a roster.
Devonta Freeman, RB, Atlanta Falcons. With rookie running back Tevin Coleman dealing with a rib fracture, Freeman is the lead back in Atlanta for now. He will see significant carries and is worth starting in most leagues, especially if you lost Eddie Lacy for this week and someone beat you to James Starks, which brings me to....
James Starks, RB, Green Bay Packers. Eddie Lacy may miss time this week, which makes Starks the lead back in Green Bay if it does happen. He should put up decent RB2/flex numbers, so grab him and start him if needed.
Lorenzo Taliaferro, RB, Baltimore Ravens. I'm a huge Taliaferro fan, and now that he's healthy, he should be on your roster. He might not eat into Forsett's workload too much yet, but by the end of the season, he could have a significant load. He's worth a stash for future weeks.
Rishard Matthews, WR, Miami Dolphins. Matthews has looked solid so far this season, and has greatly outperformed Kenny Stills. Matthews looks to have carved out a significant role in the Dolphins offense, and is worth having on your roster for this week and in the future if you need help at WR.
Gary Barnidge, TE, Cleveland Browns. This one is largely a speculative suggestion. However, in week 1, Tyler Eifert dominated against the Raiders. In week 2, Crockett Gillmore had a dominant game, against the Raiders. This week, a Browns tight end could have a strong week against Oakland. If you're grasping at straws, there are worse options than Barnidge this week.
Seahawks D/ST. I'm not saying that the Seahawks defense is available in your league. If there are intelligent people in your league, they are not. That being said, start them this week against an anemic Chicago offense with no Jay Cutler. Kam Chancellor's return suggests a possible return to dominance for Seattle. If you have a chance to pick them up cheaply, now is the time.
Falcons D/ST. The Cowboys could be in for a very rough game with injuries starting to pile up. I expect the Falcons to destroy Atlanta this week defensively, and put up some solid fantasy numbers. Brandon Weeden was a turnover machine in Cleveland. While he will generate fewer turnovers in Dallas, the potential is still there. If you're streaming defenses, this might be a unit to use.
Hope this helps, and good luck in week 3!
