I think at this point Giles will play whatever minutes Joerger feels he's earned. At this point, he's either totally healthy or he's not. Lets remember, he did play the last third of the season at Duke, and his minutes were increasing as the season went along. He's been prodded, measured, tested and retested. He's practiced with, and against his own teammates. So at this point, I doubt he'll be on any kind of health or injury restiction, unless something pops up.
If they were going to do the restriction thing, they would have played him last season and done it then. If he's not ready to go at this point, then they might as well forget the whole thing.
