Each week of the NFL season has actionable information for fantasy managers. I'm here to share some of the most important trends that impact IDP player value.

LB Jack Campbell remains the third option in Detroit.

This one is pretty simple but incredibly frustrating. Teammate Alex Anzalone has played 95% of defensive snaps this season, with Derrick Barnes playing 56% of snaps and Campbell playing 42%. Campbell still helped fantasy managers that started him by earning 5 tackles and a sack, but this was an above-expectation performance given the usage he earned. Campbell will remain an inconsistent starting option until he earns a larger role in this defense.

Green Bay LB De'Vondre Campbell left his Week 3 game with an injury.

He played only 11 snaps before suffering an ankle injury, which caused him to miss the remainder of the game and miss practice on Monday. His replacement was Isaiah McDuffie, who played 61% of snaps and earned a tackle efficiency of 16%. McDuffie was not a full-time player after Campbell exited, so his floor is slightly lower than a typical linebacker handcuff, but if Campbell misses Week 4, McDuffie can be added and started in deeper formats.

San Francisco LB Dre Greenlaw is day-to-day with an ankle injury.

He played 84% of snaps before exiting the game. His replacement was Oren Burks, who played a total of 42% of defensive snaps and earned an insane tackle efficiency of 23%. If Greenlaw misses time, Burks can be added off waivers and become an immediate starter for most teams. This 49ers defense just churns out productive fantasy linebackers.

Houston rotated the LB2 position with Denzel Perryman out.

Last week, I mentioned that Christian Harris was losing playing time to Henry To'oTo'o. With Denzel Perryman out during Week 3, managers were hoping to see Harris play more snaps. The coaching staff thought otherwise. Blake Cashman played more snaps than Harris, showing that he is fourth in the pecking order for linebacker snaps on this team. To'oTo'o played 95% of snaps, Cashman 63%, and Harris 62%. This is a sign for managers to move on from Harris, except in the deepest dynasty leagues. As soon as Perryman returns, Harris' snaps will plummet once again.
