I think you could probably find a few guys you could take a chance on. Maybe plugged into Detroit's system they look better on defense than they previously did.
I mentioned Ayo Dosunmu a few days ago, he could be one of those guys. He will never be a good defender, but he could be a guy that isn't hunted in the playoffs. When you shoot 44% from three, that is acceptable defense IMO.
You could maybe get him for a couple of seconds. Worst case is this year's first. He is a free agent this summer so its an easy out if he doesn't work out.
