With all due respect, there are so many things wrong here, that it is bewildering.With all due respect... not a chance in hell.
As much as I like Kessler, at this point there's no way anyone would part with a lottery pick for a non-shooting, soft center with pretty meh athleticism who's hitting .547 from the FT line and can't switch anywhere close to the perimeter. He's played well overall for a rookie big, but to bring back a lottery pick, he'd have to have a much higher ceiling. Kessler may become a guy with that kind of value in the eyes of NBA GM's, but he's not that player yet. Rim protection is valuable in this league, but Kessler still has some huge weaknesses that really limit how much he can be a part of a modern NBA offense.
As for Vanderbilt, his stock is dropping, not rising. Frankly, his RAPTOR numbers are straight up shocking. In fact, it could be argued that he should be out of the rotation altogether if we're trying to win. At the very least he should be sent to the bench because his fit in our starting lineup is terrible. Now, I guess it is possible that there's a few teams in the league with plenty of firepower that could be willing to try to replicate Vando's Minny role and trade for him. But for a FRP? He's not a difference maker.
Beasley will always have a job in the NBA because he's a shooter who can get red hot. Unfortunately he's has been awful lately, which hasn't helped his stock, but Beasley is still the only one of these three guys who could probably bring back a reasonable FRP right now if a team desperate for scoring came along.
Kessler is an astonishing athlete for a seven footer; if he is meh, then 95% of all 7 footers in the NBA are outright atrocious. It is extremely hard to say what his ceiling is, as he has only just shown his floor. Shooting is a skill many NBA players not called Ben get better and better at; not all are Jimmy Butlers, but most get way better than they are in their rookie year. Kessler most certainly would for a trade to happen need a lottery FRP plus a roleplayer.
RAPTOR, being a box-score based stat, is an incredibly poor meter for players like Vando, who do all those small things that glues a bunch of players into a team; the hustle, the energy, the ability to improve those around him are not shown in RAPTOR or similar stats. Mk 1 eyeball test seems to suggest his value is in fact increasing, and most definitely a FRP would be needed to move him.
The league knows who Beasley is. A few good or bad matches doesn't change that. His value is not going to fluctuate anywhere based on a slump or redhot strike; he might in fact be hard to move for any decent return, most likely if he is moved it will be as a filler in addition to someone else.
