Ant has the perfect skillset for a modern day point guard. Ultra quick, gets where he wants to go, and can shoot "theoretically".
But the problem is results. He shows moments of competency like the few drive and kicks he had. That's what he should be doing all the time. But on most possessions he spends half of the shot clock directing traffic only to realize there's only 12 seconds on the clock and he has to make a move. The offense just doesn't run.
Also, the bigger issue is that he's just not been effective at all. All the athleticism and quick moves to get himself open - they look pretty - but he can't finish. He's a 30% 3 point shooter, on a lot of open looks, and his finishing at the rim is even worse. I'm sorry, putting the ball in the hoop is his theoretical skill, but if he can't actually do that, then what is he doing on the floor?
