I doubt it. WRs don't really slide like that over the last couple years. See treylon burks terrible combine and him still being drafted esrly
You're not wrong about the positional value and the fact that WRs don't slide. That comp with Burks, though, is a bit rough. Burks was a physical specimen that won people with his potential. As an aside, I was never high on him and caught some crap for it. Anyway, with JSN, he is pretty slow for a WR with an alleged 4.6 speed. He is coming off a year of injuries with little to no production and rumors that he could have come back and played but checked out for draft prep -- which is his prerogative, but the optics don't play well.
So, he is not a physical specimen by any stretch of the imagination. I'm forecasting his actual measured height to be around 5'11" once the college round up is removed. So, injuries, lack of production, lack of measurables, and the ability only play one position, which, to be frank, not all teams consider slot to be a starting position. I mean, I get it, in today's one back set, the slot is considered a starting position, but it can be filled by a flex TE, a motioning back, or a big WR trying to post up. He's not a gamebreaking WR. He's not. He's a glorified possession receiver: the reincarnation of Waddle.
So, though I believe he should be considered WR1 for this draft, I think he is going to be the only R1 talent to fall out of R1. I see Skoronski falling into the late teens, early 20's, but not out of the first. JSN? Yeah, he's going to drop. It may allow us to get him with what we can get from a trade back. Him falling is a very good thing for us.
