Jazz let Lauri yesterday go to Arizona for the alumni day there, as there is nothing spesific Jazz needs from Markkanen at the moment, and he is just expected to be with the team in Toronto tomorrow. Kinda weird timing, if you ask me, what with the team seemingly working their butts off in front of their new coach.

Also, the last Jazz tweet mentioning Lauri is from September 27th (when he met JV and most of the team for the first time). All other 18 Jazz team members seem to have been mentioned in Jazz tweets since then.
I have a hunch Lauri Markkanen will be included in a trade on November 8th (the earliest date he can be traded unless exactly one for one, which certainly isn't what Jazz is looking for), and Jazz is atm trying to avoid building any kind of hype around him.
