Not fully relevant to your post, but I really don't like the "no talent at the end of the round" argument. Sure, it's more difficult to hit on those pics, but there's plenty of talent there.
Starting from 2015, the last time before this year we had a 1st rounder: Landon Collins, Devin Funchess, Jalen Collins, Bernardrick McKinney, and Eric Kendricks could have all been realistic targets for the 1st. Tyler Lockett, Tevin Coleman, Duke Johnson, Jordan Hicks, Tyler Kroft, and David Johnson realistic for the 2nd. Daryl Williams, Jamison Crowder with a few spots of Geneo Grissom in the 3rd. 4th was hit in both rounds. Grady Jarrett, Adrian Amos, Stefon Diggs, Jay Ajayi, Cedric Thompson all in the 5th round. Obviously, we didn't all know that they would be good players, but there's always talent - the team just has to find it.
In 2014, our 1st was a big bust. Others within a reasonable space were Bradley Roby, DeMarcus Lawrence, Joel Bitonio, Jordan Matthews, Lamarcus Joyner, Weston Richburg, Tuitt, Trent Murphy, Jernigan, D. Adams. 2nd was hit... I guess, but players like Christian Kirksey, Trent Murphy, Gabe Jackson were also near there. By our next pick, we could've gone with Martavis Bryant or Tre Boston. Players that we could've easily gotten if necessary later include Telvin Smith, Aaron Lynch, EJ Gaines, Duvernay-Tardif, Enunwa, etc. Again, not star talent everywhere, but we could've gotten key players despite our position.
2013, Instead of Dobson with our 2nd rder, we coulda gone Kelce, Lacy, Mathieu, Terron Armstead, Keenan Allen just a bit away. In the 4th, Alex Okafor, David Bakhtiari, Gerald Hodges were also there and taken within a dozen or so picks.
2016, rather than Cyrus Jones with the 2nd rounder, we coulda gone Byard, Ngakoue, Kenyan Drake, all within 15 picks later. Instead of Valentine, Justin Simmons, Joe Schobert were there. Sprinkle Tyreek Hill in there too.
Overall:
Cyrus Jones -> Yannick Ngakoue
Malcolm Brown -> Bernardick McKinney or Landon Collins
Jordan Richards -> Danielle Hunter or David Johnson
Geneo Grisson - Daryl Williams
Tre Jackson - Stefon Diggs or Grady Jarrett
Dominique Easley -> DeMarcus Lawrence
Bryan Stork -> Martavis Bryant
Cam Fleming -> Telvin Smith
Dobson -> Kelce or Allen or Mathieu
Pick 2 or 3 of those swaps and this team looks different. There is talent around the draft, even within a dozen spots of where we may make a bust draft pick.
