I enjoy reading him, but I honestly think at this point half of Demakis's hyperbole is him playing up his reputation for it. Regarding Lonzo, "It is difficult to envision him becoming less good than Nash." And "Fultz is a hybrid of Dwyane Wade and James Harden with potential to be better. It is almost easier to see him becoming better than those two than worse." The first comment to that article is pretty hilarious.
I think he's too high on Monk, Fox and Markkanen. I love a lot of Fox's game, but his jumper is Rondo-esque broken, which very difficult for a PG to overcome. Markkanen, on the other hand, has one of the sweetest and quickest strokes I've ever seen from a big, but he doesn't do anything else. He has quick feet and a good frame, so maybe he could develop into an Olynyk-like team defense skill set, but from what little he has shown so far, he'd have to be incredible on offense to make up for his defensive deficiencies.
