In the Eastern Conference they'd both have a shot. Maybe even Favors too, if he keeps progressing.
If Gobert puts up 16/12/2.5as/2.8bl-type numbers, that would put him near Dwight Howard and Alonzo Mourning territory. Those numbers are also better than what Marc Gasol puts up. He'd have to be in the discussion even in the West, though Gasol might still get the nod.
Keep in mind, Gobert had a run last year where he was putting up 16/14/2as/3blks. If he'll make his free-throws he can score 18ppg. He'll get a lot of attempts.
