Carl:
EHills has a lot of up-down-up to it; tees that are elevated, to fairways below, with greens perched (severely, in a few cases) above the fairway. So in the main, I don't think we'll see too much ground-game approaches into greens. You definitely won't see it at 3, 4, 7, 8, 9, 10, 11, 13, 14, 15 or 16.
Interestingly, the four holes perhaps best suited for it open and close the round -- the curving par 5 1st, where the hole sort of flows into the green, and fun and short par 4 2nd, with a tiny, inverted tea-cup green that maybe the pros might be a bit intimidated spinning a wedge for the approach. I saw a variety of approaches on the ground during the US Am a few years back.
I can maybe imagine a ground approach on 17, the long par 4 with no bunkers, and the long par 5 18th, in part because those holes may play with the prevailing wind, and I can see an imaginative player not going aerial on those holes going at the greens.
Maybe ground approaches into 5 and 6 (front pin only) -- again, holes playing with the prevailing wind -- and maybe on 12, which is the rambunctious par 4 with trouble around the green, but open in front.
