Need help deciding on WRs/flex (should I bench AJ Green?)

PPR

My options:

AJ Green @ Ari
Alshon Jeffery vs Den
Sammy Watkins @ NE
Jonathan Stewart vs Wsh
Karlos Williams @ NE (not really considering him though)


So I need to pick 3 of these (at least 2 WRs) and I'm having trouble.

Jeffery and Watkins had horrible games last week but Watkins still had a decent amount of targets and he has a good matchup this week. Jeffery has a bad matchup but I still feel uneasy about sitting him considering he has put up great numbers in all the other games he's played in.

AJ green also has a tough matchup and has been underwhelming in all but two games this year. He had 44 week 3 at Baltimore and had 28 week 8 at Pit. Other than those two weeks, he hasn't scored more than 15 points this season. I know, start your studs. But he hasn't been much of a stud this year. Mainly just meh.

Stewart has a decent matchup and has been solid. But he doesn't get a ton of yards (only had over 100 yards rushing once this season) so I'd basically be gambling that he gets a TD.

Any insight/help would be appreciated
