With the amount of 3-4 WR sets they run, they’re going to need depth. I'm still not sure Beasley is even going to be around next year, but with no splash signings and the return of Lil’ Dirty, who knows?
You could argue, this team always carry’s 6 WRs on the active roster. Right now, you could look at it and say
1) Diggs
2) Davis
3) McKenzie
4) Beasley
5) ???????
6) Kumerow*
They need at least one viable option, and probably 2. I fully expect them to take one at #25 and possibly pick up another vet option, like crowder, Pringle, Higgins, etc.
*it’s possible he fills at “ST only” roll, as did Taiwan Jones. He was a RB by nature, but wasn’t necessarily counted as such when looking at the formation of the roster. That being said, Kumerow did take plenty of offensive snaps last year in heavy packages. He could genuinely be #6 in their mind.
