Oh yeah, "this time is different!"
There is simply no precedent for all top 5 draftees to turn-out into consistent high-impact players if you look at the draft history. And I am talking about top 5 drafted in June, not who was considered the top-5 in March.
Just to illustrate, here are the duds from the top-5:
2010 - Evan Turner, Derrick Favors, Wesley Johnson
2011- Derrick Williams, Enes Kanter, Tristan Thompson, Valanciunas (achieved nothing in his first 7 seasons and got traded by his original team)
2013 - Bennet, Otto Porter Jr., Cody Zeller, Alex Len
2014 - Jabari Parker, Dante Exum
2015 - Okafor, Hezonja
2016 - Bender, Dunn
2017 - Fultz, Josh Jackson, Lonzo Ball (due to injuries)
2018 - Ayton, Bagley
2019 - De'Andre Hunter
2020 - Wiseman, Patrick Williams, Okoro
You can keep telling yourself that all top 5 draftees will turn out to be impact players but the experience tells us that most likely two of them will end up being duds, i.e. unremarkable, middle-of-the road players or worse.
Congrats on spending a lot of time researching that post just to “prove somebody wrong” on a message board.
To be clear - I am not saying I would bet on all 5 turning into high-impact players in the NBA. To your point, busts are inevitable. But looking at each player individually? I’d bet on NBA success for each of them.
When I look at my own top 5 right now - (of course we don’t know who actually gets drafted top 5 in June yet) - I would be surprised if any of the below are a bust at the NBA level:
Cooper Flagg
Dylan Harper
Ace Bailey
Tre Johnson
VJ Edgecombe
IMO, this is the best tier of top talent in a CBB freshman class in at least a few years - perhaps several. And unlike a few names on your list, among this group, nobody is a “project,” relative unknown in some foreign pro league, etc. They’re all very talented players who are extremely productive as freshmen (at the highest levels of CBB) and have the physical tools / athletic profile that *should* translate to the NBA game.
This is not revisionist history (I *****ed on last year’s class relentlessly) - a top 5 pick last year vs. this year is night and day. I would have traded very little of value for the #1 pick last year. This year? #1 is untouchable, 2/3 would take a King’s random, and 4/5 (perhaps 6/7 - beauty is in the eye of the beholder with Kas and Maluach) remain quite valuable.
