pisgah101, good post, and very interesting question. Couple of things to look at here: If there were no chance to get into the first four spots (double bye), I would rest them both and go all in for the NCAAT, because without the double bye, Grayson and Amile probably won't make it through the ACCT (just too many games in a row), let alone NCAAT.
Now, "K" is thinking about this scenario right now, and probably discussing with his Staff. My gut instinct tells me that if Grayson is ok Tuesday, he will play, but Amile will sit this one out. Since it is Senior night, Amile will probably start and take a seat at the first time-out. It will be put on Giles & Bolden to carry the post area, and that's not a bad thing. Time to shine Harry!
The reason I think Grayson will play (if he does) is that there is still a chance (with help) that we can still get one of the four top spots. I'm not being pessimistic, but I don't believe we can win either of the last two games without him.
Please keep in mind that this is just my opinion & gut feeling and will probably happen just the opposite of what I have said

! This is why "K" makes the Big Bucks, and I can tell you, he wants to finish strong as much or more than we do, I know that.
Go Duke!
