I would 100% be willing to draft a WR, CB, S or DE if they were the best player available when the Browns are picking in the first round even though the Browns have young talent at all of those spots.
We'll see how this season plays out, but there's only one really glaring need on the team right now which is a really good heading into free agency and the draft.
Personally, given how much young talent we have at WR right now, I don't think I'd waste a first on a receiver. You can find elite receivers in the second and third round.
Hell, look at last year's draft.
Corey Davis - Fifth overall...shown a flash here and there but nothing yet.
Mike Williams - Seventh overall. Rookie year was basically lost.
John Ross - Ninth overall. Wasn't even good enough to get on the field for the Bengals last year.
Zay Jones - 37th pick. Did next to nothing last year and can't beat out Kelvin Benjamin.
Curtis Samuel - 40th pick. So good the Panthers used a first rounder on a WR just a year later.
The three best receivers thus far from last year's draft were picked 62nd (JuJu), 69th (Kupp), and 84th (Godwin...buy him now in fantasy before his team realizes he's better than Mike Evans). Might also include Golladay (96th pick) and Westbrook (110th). Also, I didn't look at undrafted WRs from last year, so there might have been another example or two out there.
Either way, unless Gordon washes out of the league again, I don't really see a reason to invest a first-rounder in a WR when there's always elite WR talent to be found later in the draft. Always.
