I wrote part of this yesterday and then the rest of the day got nuts. Sorry for the late answer here.
Well, I think we’re screwed no matter what we do, so I’m trying to plug holes on a leaky ship.
I don’t think the combination of Keim & Kliff will ever win anything of importance so I don't want to make moves that are beholden to Kliff's system in the long term. Green to me seems like the perfect compromise to getting Kyler another weapon (one who is actually proven) and seeing if that helps step his game up, while not swinging and missing on a young WR so high that we find ourselves in 2021 having to replace someone young yet again.
A WR room of Jeudy/Lamb, Kirk, Isabella, Butler, and Johnson in 2021 freaks me out because I literally have no clue if any of those guys are any good, and they're probably all sub-1,000 yard receivers at that point.
