We're halfway through the fantasy football season, and there's a lot of things to keep track of heading into Week 7.

Between bye weeks and injuries piling up, it's hard to determine who to play in any given week. For leagues with a flex position, there is a whole added element in determining which running back, wide receiver or tight end to play. 

Here's a look at four players who would be good flex options in Week 7. 

 

Donnie Avery vs. Cleveland

Avery had four catches for 60 yards in the Colts' loss to the Jets. Andrew Luck and the entire Colts team was taken by storm, but will be looking to bounce back against a relatively weak Cleveland team.

Browns CB Joe Haden is back from suspension but will be covering Reggie Wayne all game. Avery is pretty talented and could be a decent flex play. 

 

Mario Manningham vs. Seattle

Manningham got a season-high 10 targets in Week 6 and turned those targets into five catches for 72 yards. Although Seattle has had a stingy pass defense, the Seahawks were lit up by Tom Brady for 395 yards and two touchdowns on Sunday.

It should be a close game, so the Niners will be putting the ball in the air a lot. Alex Smith is no Brady, but he can still put up some good numbers and get Manningham the ball. 

 

Daryl Richardson vs. Green Bay

Slowly but surely, Richardson has eaten away at Steven Jackson's carries. At this point, it's almost an even split. That split could continue to swing in Richardson's favor if he produces at a high rate.

Against an extremely good Miami run defense, Richardson had 76 yards on just 11 carries. He also caught two passes for 23 yards. Richardson is a very solid flex play against Green Bay next week.

 

Brandon Myers vs. Jacksonville

Myers has quietly become a reliable target for Carson Palmer. He had five catches for 62 yards against a solid Atlanta defense in Week 6. He has 16 catches for 228 yards on the season.

The door is wide open for Myers to rack up the targets. Oakland faces a poor Jacksonville pass defense in Week 7, so Myers could have a big game.
