He is either going to be on schlolarship or he isn't. I don't see how grayshirting would even work with basketball.
Well, I'm just spitballing because I don't know how it works but I would think it would be legal to have him enroll part time his first semester as a greyshirt, redshirt second semester and then be essentially a RS freshman the next year. I don't see how that helps anything, however as he would still have to be in the same class.
