might be the case but that seems like assumption at this point
Ant is "producing at a high level" because he's taking a lot of shots. He's averaging 6 more points/game and 4 more FGA/game. so that increase in production is welded to a simple increase in shot opportunities. If Ant 'qualified', he'd be 11th in scoring but 6th in FGA. The rest of the NBA can do that math.
and I'm not sure how much 'producing as a #1' on a bad team enhances a player's value. And, Ant has only played in 11 games, 8 or which were at home. And, Portland's record without Ant is 7-13 (.350) and with Ant is 2-9 (.182). Portland's record is 9-18 with Grant; 2-9 with Ant. And yes, these are all small sample sizes but all these might be some of the gauges a team uses when deciding what value to assign Ant
to be fair, Ant has actually ramped up his efficiency a bit while increasing his usage and shot attempts. That's less common than the opposite. But to this point Ant hasn't positively impacted Portland's record with his increased production; that outcome has been the opposite as well
