Good point about Wicks. It's more likely that Melton, Heath, and Hardman don't make the 53.The only scenario I don't see Wicks on the 53 is if he gets injured or traded. Wicks is at worst our #4 and probably #3 at least starting week 1 ( fighting with Golden) Reed and Doubs are #1 & 2 out of camp)
With the scenario you pointed out, that leaves Reed, Doubs, Golden, Williams and Heath on the 53. Who is your 6th WR? As for Melton, he is the most expendable WR with Golden & Williams added to the roster (Golden for the speed he offers, and Williams for the Jet Sweep plays) Melton had 9 total catches last year, and his 2023 numbers were inflated by 1 game where he had over 100 yards receiving. Hardman at least offers Special Teams return ability and is fighting Heath for the #6 spot, Melton as of now is my #8.
Watson doesn't count in any of this, as he will be on IR to start the season. When he returns, someone on the WR roster will get traded, released, or put on the practice squad.
That still leaves the problem of only having 5 WRs - assuming no changes in personnel and Watson unavailable until late October. To fill that gap I'd keep Melton. Yeah he only had the one good season, but that's more than Heath can say, and Hardman is a PS guy. Nixon wants to return KOs again, and I don't think they keep Hardman just to handle PRs.
