Yes, there have been very good, fast receivers. I believe i said top-10 40 times? I also should have added that the times i saw were from the combine so that obviously excludes a number of players who had insane speeds at pro days.
Now I feel forced to look it up, here are the top 40 times in combine history. Some good players but most are, uhmm, forgetable:
John Ross 4.22
Kalon Barnes 4.23 (CB)
Rondel Menendez 4.24
Chris Johnson 4.24
Jerome Mathis 4.26
Dri Archer 4.26
Tariq Wooden 4.26 (CB)
Henry Ruggs III 4.27
Stanford Routt 4.27
Marquise Goodwin 4.27
Champ Bailey 4.28 (CB)
Jacoby Ford 4.28
JJ Nelson 4.28
Tyquan Thornton 4.28
Ignoring corners (they're not really the point) you have one great WR, one great RB, and one potentially great WR (Ruggs)....40 time is important but just being one of the fastest isn't a great indicator of potential performance.
Most of those don't even have a "career" to gauge really and that is why I stayed in the same position and only guys that actually have some years under their belts to judge. Your list includes other positions but using it lets look at the guys:
WR John Ross 4.22 - Purely a depth contributor role type guy, arguably less value than MVS would be agreed.
CB Kalon Barnes 4.23 (CB) - Hasn't played a snap, zero reason to judge.
WR Rondel Menendez 4.24 - A 7th round draft pick (so zero expectations of good), showed promise as returner and then tore his miniscus zero ability to properly judge in many ways.
RB Chris Johnson 4.24 - Had a very electric, somewhat short career - 6 straight 1,000 plus seasons is insanely good, and was supportive role for two more before really dropping.
WR Jerome Mathis 4.26 - As a rookie this dude LIT IT UP as a returner, making the Pro Bowl even...in his second year he fractured his foot and was never the same...showed insane promise but no one can judge his career as he never had one.
Dri Archer 4.26 - Decent returner but never great and never panned out into anything after being a 3rd round pick. *Failure can be applied justly it seems.
Tariq Wooden 4.26 (CB) - Hasn't played a snap zero reason to judge.
Henry Ruggs III 4.27 - Will never know, zero reason to judge as cannot incomplete
CB Stanford Routt 4.27 - Eight year career, was a starter three of those years and wasn't a a terrible CB to have but also not a top end as many hoped. Failure may be harsh but definitely underachieved.
Marquise Goodwin 4.27 - This guy is still going at age 31 and has seen 9 seasons of use. He's been primarily a role type guy, with 2017 nearly breaking 1,000 yards receiving...but for a 3rd rounder slight underachievement I think any could argue as enough of his career has passed. Last season he put up 313 yards, was not a starter and scored a touchdown for Chicago.
CB Champ Bailey 4.28 - Everyone knows this guy, VERY good.
Jacoby Ford 4.28 - A fourth rounder that was christened a return specialist that happened to be a WR as well. Despite that he did put up 470 yards his first year and an 18.8 yards per catch level. However after three years and growth by others his "specialty" role was a liability to a roster space and was cut, never picked up elsewhere - similar to others being a 4th and never even staying on a roster elsewhere after a few tries even in the CFL and failing he is christened a failure with justification.
WR JJ Nelson 4.28 - A 5th round flyer taken by Arizona in 2018, he is actually still in the league technically...but after PS squads since his knee injury it is doubtful he is picked up. Crazy thing is Nelson appeared to be growing into something in first three years putting up over nearly 1,400 yards, seeing over 75 receptions but his catch percentage was worse than even MVS (partially comes with the fact he was a deep threat only role type guy). Not being one good at returning this limited his function and once rookie deal was done his future was as well. For a 5th rounder one could argue he did what could be expected and even flirted with being more.
Tyquan Thornton 4.28 - Hasn't played a snap zero reason to judge
