A few prospects?! Literally ALL MVPs in the last 10 years came outside of top-10 in the draft. And here is the number one picks in 2011-2020 (those that are still in the league and had enough time to pan out): Irving, AD, Bennett, Wiggins, KAT, Simmons, Fultz, Ayton, Zion, Edwards. Do you see many successful franchise players here? During the same period the following players were drafted outside of top-5: Kawhi, Lillard, Butler, Giannis, Jokic, Booker, Sabonis, Siakam, Mitcell, SGA...
Take the 2012 draft, for example: the GMs in their eternal wisdom identified prospects with the most franchise-player potential in Anthony Bennett (1), Victor Oladipo (2), Otto Porter Junior (3), Cody Zeller (4), and Alex Len (5), while deeming Giannis (15) and Gobert (27) as clearly lacking that coveted potential despite both of them clearly being incredibly tall and athletic players.
The GMs and fans are incredibly bad at identifying players with the franchise-player potential unless they are dealing with tall athletic freaks like Shaq, LeBron or Wemby.
