Noah Brown has been out these two games and that has definitely helped.
Since CJ has started popping off in week 9, Nico has played two games and in those two he has had strong showings.
They do have tougher matchups coming and have 5 capable receivers but have to reel that with Tank’s emergence, Nico could get more favorable coverage.
Is he a must play every week?
As a Collins-haver, I wouldn’t say that he’s a must-play every week once Noah Brown is back. Definitely a no-brainer top-20 WR option in the vast majority of matchups with Brown out (or if Tank were to miss time), and still a top-30 guy with Brown in but at that point you might have better options depending on your players’ matchups that week.
