I think WR's are going to go earlier than people think this year and it may even be the start of a long term trend now that it costs so much to retain your vets.
There are teams out there desperate for WR help, but there are also a lot of teams that have good WR's that expect a huge pay raise. With the way the WR pay scale is going to change it will be interesting if WR's turn into RB's-light. With RB's it makes sense to take a day #3 guy every year and take a flyer on an undrafted RB. With WR's I would think teams would be drafting one on day #2, and take a flyer sometime on day #3. In a pinch maybe you add veteran depth without breaking the bank on FA(or WR finishing their rookie deal early).
In 2020 you have Tee Higgins, Chase Claypool on day #2 of the draft. In 2019 you have Deebo Samual, AJ Brown, DK Metcalf, Diontae Johnson, Terry McLaurin. In 2018 you have Courtland Sutton, Christian Kirk, DJ Chark, Michael Gallup. In 2017 you have Curtis Samuel, JuJu, Cooper Kupp, Chris Godwin, Kenny Golladay.
I'm not saying that it's easy to pluck out a #1 WR every year, but just pointing out that in almost every draft there are very talented guys at the WR position in the 2nd and 3rd round. Sure, maybe you find a Kupp or AJ Brown and pay them the big second contract if it makes sense but for the most part just take a swing on day #2 every year and you'll probably have a fairly good top 4 receivers without having to break the bank to retain them.
The more I dig into the WR class this year the more I'm convinced that EVERY YEAR is a strong WR year..... you just have to have the scouts to find them. This isn't like the QB market where you can only develop one guy at a time.
