One important caveat here is that of the three WR positions (X, Y, Z) two of them allow for motion so it is normal to have most of your receiver corps be non-X types.
Britt is going to be X plain and simple. Behind him it will be Quick vs Thomas and North. Split end starter plus depth is the extent of it on the roster concerns, will probably be two guys with the other four being combination Y, Z types.
Tavon is going to own Z. But he'll move around too, so they'll have those other four guys mixing and matching primarily at the slot but not just there.
So just IMO the X types will be Britt and Thomas. I am of course higher on Thomas than North and I think Quick lacks special teams impact, will be more expensive moving forward, and is out of time. Quick is gone and maybe even in an early cut.
The Y & Z types will be Tavon, Cooper, Marquez, Spruce. Marquez makes it due to teams, and Spruce is also a good teams guy so both will earn roster spots. Cooper is going to start in the slot IMO.
