There are at least 3 key positions open for 2019. The KC RB, the Jets #1 WR, the Colts future #1 WR (sooner than later).
After that, there's a good chance that the RB position is filled in this class in BUF, NYJ and HOU. Bucs may make a move at RB as well.
ARI will draft a big WR is my guess.
The Bills need WR help bad.
CLE may take a big WR.
The 49ers will draft a receiver but he will be fast and underdeveloped, pull hamstrings and have other injuries but he will be fast when he's out there. RB as well.
If these are not filled, then they will be filled in the 2020 class which does indeed have some serious talent at both WR and RB.
Also there are opening in BAL for WR ...bleeccchh. MIA - QB position in flux, then there's OAK with all kinds of openings for the taking.
The Lions will take a WR and he will be as under utilized as Golladay. They will take a TE and not use him at all as the can't get enough of Theo Riddick greatness.
