If Yabusele refused to be stashed for an extra year, he'd make an intriguing sweetener here as well and we could get off his salary.
Then you are trading two recent 6 + 16 picks for 12. This has no sense.
It makes perfect sense: draft picks suffer from new car syndrome unless they have flashed previously unexpected potential. Their value plummets once they step on the court. (This may be less true for Yabusele since he hasn't actually played yet, but he was a massive reach at #16 to begin with.)
Jaylen Brown, for example, would barely net you #10 in this draft despite the fact that he's had a pretty good year. That's because a lot of the value of a draft pick is tied to the small possibility that the player you draft is a generational outlier and blows up completely beyond expectations. Once that lottery ticket value is gone and the player is just a player, they're just not as valuable.
OMG
By the way, only time will tell if Yabusele was "a massive reach" at 16. These reckless statements can be refuted as years go by. Way too early.
I think he's exaggerating and don't agree with his specific statements about Brown or Yabusele, however he is correct in that unless you are talking about a guy who is already an unquestioned star talent, GMs often fall in love with the MAYBE potential of the draft pick over the player already drafted.
I think in Brown's case he definitely has shown enough, especially later in the year, to be valued somewhere in the 3-8 range. However, he's not a sure thing by far, so it would be more of a case-by-case basis on how each GM views him.
The idea is that, once someone is in the league, if they really have that superstar potential they would have shown it very early. If they haven't, then you might as well draft someone that is an unknown but still has that small possibility of being a star.
Also, there's the fact that you would always prefer to get four years of someone on a cheap contract rather than 2 or 3.
