Derek Carr, QB, Oakland. If Carr is still available, grab him, since he is going to be your best option at the position if you need to add somebody. He's looked solid with the Raiders this year, and could be a starter on at least some fantasy teams. If you need help and he's on waivers, get him on your team.
Blaine Gabbert, QB, San Francisco 49ers. Kaepernick has been benched in favor of Gabbert. While you're in trouble if you need to start Gabbert, he's at least there as an option. I don't expect huge numbers from him, but if you're reaching deep, Gabbert is an option. In many leagues, the market is pretty slim at this point, so roll the dice here.
DeAngelo Williams, RB, Pittsburgh Steelers. Somebody probably dropped Williams after Le'Veon Bell's suspension ended. Now that Bell's season has ended, get Williams on your team. This is a move that could help you win a league. This is the first move you want to make this week.
Jeremy Langford, RB, Chicago Bears. With Forte injured and expected to miss at least one or two weeks, Langford could be an option here. If nothing else, this is a good opportunity for Chicago to see what they have in Langford. Give him a shot if necessary.
Chris Polk, RB, Houston Texans. This is a speculative add, but Alfred Blue was average-at-best while replacing Arian Foster last week. Polk could earn more playing time, and that in turn could make him a worthwhile investment at RB. If nothing else, he's worth a grab to sit on your bench in case he takes over.
Tavon Austin, WR, St. Louis Rams. Tavon Austin had a solid, solid game last week. While he's very big-play dependent, he also has the upside to be a nice flex play on a near weekly basis moving forward. If you lost Steve Smith to injury, Austin could be a nice fill-in.
Ted Ginn Jr., WR, Carolina Panthers. I love Ginn Jr.'s potential to continue to perform this season. He's had a breakout season of sorts, and has at least produced consistently in a week-to-week fashion. He's not a guy that will win you a matchup on his own, but he'll at least provide consistent points.
Robert Woods, WR, Buffalo Bills. Woods is here because of the injury bug in Buffalo. Watkins and Harvin are still beat up, and Woods looked good before Buffalo's bye. While the WR position in Buffalo has been a revolving door of sorts this year, Woods is worth a long hard look, especially in deeper leagues.
Vernon Davis, TE, Denver Broncos. News flash. Vernon Davis will now be catching passes from Peyton Manning. If anything can save his season, that fact can. Davis could be available in your league. If he is, get him on your roster, especially if you need TE help. He might not produce big numbers, but the potential is there.
Heath Miller, TE, Pittsburgh Steelers. Miller has faded in recent weeks. However, with Roethlisberger back in Pittsburgh, Miller once again had a big week. Miller's best weeks of the season came with Le'Veon Bell missing from the lineup. Coincidence or not, if Miller is available, he's a potential source of help for your fantasy team.
Ben Watson, TE, New Orleans Saints. Watson is finally looking like the #1 TE in New Orleans. With the New Orleans offense finally coming to life, it's a good time to own Watson.
Atlanta Falcons D/ST. The Falcons are facing a 49ers offense lacking Vernon Davis and starting Blaine Gabbert this week. With Gabbert lacking options to throw to, this could be a big game for the Atlanta defense.
Jacksonville Jaguars D/ST. The Jaguars are facing a Jets offense with lots of question marks, mainly surrounding injuries at the QB position. That could make for a big week for this unit. The Jaguars have some great pieces on their defense, and this is one week where they could put up some solid numbers.
Hope this helps, and happy streaming!
