I can't agree with you there.
Heading into that 2023 draft, the Packers had two guys on the roster who were worth any sort of consideration at receiver-- Watson and Doubs. Virtually the entire WR corps was built in that draft (Reed, Wicks, and Dubose), via UDFA (Heath), and a SFA (Melton). The only other player who made the roster at WR and who was on the roster before that draft was Samori Toure.
Going into this year, they already have Doubs, Reed, Wicks, Heath, and Melton heading into camp. Watson is obviously still under contract, but injured.
Still a legit need, but a little less so compared to 2023.
Now an argument that I could see is draft position. In 2023, they picked 13th and JSN went 20th. So maybe they would have been interested in him later on (say, in the range where they pick this season).
