This point gets repeated often here nowadays, but nobody wants to look at the other side of this coin, which is the Luka Doncic and Mavs situation right now. Yes, focusing on winning early is good for development and "star morale" or whatever, but can you really say that it won't piss off your star even more to be mediocre early on, and get a failure of a team surrounding you for the foreseeable future?
I'd say Doncic looks more pissed off at his situation than Wemby is, though I don't keep up with the Mavs beyond general news. He's notoriously frustrated with the team on the court at times, and the Mavs have little assets to improve moving forward and no young talent to pair with Luka, as he was too good, too early. Wemby is, too, so it's a good parallel to keep an eye on.
At the end of the day, a #1 pick that gets truly frustrated or angry because their rookie team is not good, is not a player worth building around. Wemby shows exactly the opposite signs and tremendous poise, which is a big green flag in my book. Patience is rewarded.
