If he loses the lockerroom he needs to go.
But for now, I don't think he's has to go.
I feel Grier needs to go regardless of Flores does this year.
Why I feel Grier needs to go:
We traded up for a WR when there were tons of pressing needs. I like Waddle, and still do but they gave up a lot for a WR who is a complete nonfactor his rookie year. I know WRs some times need a year to develop/adjust and his QB situation was less than ideal with Brisket. But, nothing so far screams impact player/talent at the moment. Gave up a future top 10 pick, and chances are he still could of been there at 12.
Add in the 2020 draft not looking too hot, and poor FA signings to this day, we need new direction at GM.
