Grant is neither as strong or as quick as I want him to be in my mind. He should / could / we want him to be a versatile big that can credibly guard all types of 3-5. In reality, he is not fast enough to keep quick drivers in front, he is not strong enough to contain bruising 4s, and he's not tall enough to guard a 5 with any kind of post game. So basically, he can guard 3-5 but only crappy bench player 3-5s. I don't see the value there.
