Doubs and Okonowo would be a nice pair of signings today IMO.
Doubs is an outside receiver who's shown some ability downfield but specializes in intermediate routes and has some chain moving ability to him. That works well with Boutte who has really been more of a downfield guy since Maye took over. Not saying he's a #1 or some monster, but they lost their most productive receiver in Diggs and their #1 playing time WR last year was Mack Hollins even before that so there's definitely a need to fill in snaps here with proven production. Many people tout the idea of KWilliams' development replacing Diggs, but the truth is any improvement from him should have already been ticketed for eating into Hollins role because he just flat out shouldn't be WR1 in terms of playing time. So even if KWilliams develops like we all hope, still need someone to take a heavy WR snapload because we should be looking to replace Diggs since he's gone AND Hollins since he just shouldn't be a high playing time WR.
Okonkwo is a versatile move TE which can fill in some of the gaps for those slot-type routes that they let go with Diggs as opposed to last year where we played with two in-line TEs in Henry/Hooper together. Still leaves us without a strong blocking TE out of those 2 TE formations, but you become more versatile in the receiving game. Last year, even with 2 "receiving TEs", our 2 TE set didn't have a ton of route tree versatility. Henry and Okonkwo would be more complimentary in terms of the ways they can attack the defense in the passing game.
