At the time of this video, there were no cups cut into the 8 new greens. Recently, when Mr. Keiser and friends played, cups were cut on those greens, even if they weren't close to having tight, playable turf.
The long putt, down the slope and into the cup, was nearly without a doubt on one of the 10 preview greens....the ball rolled far too well and true to think it was rolling on one of the new greens. (that was Grant Rogers, btw) Those greens are currently rolling at about 9+, with some of the most beautiful fescue turf to be found. Kudos to Ken Nice and the Old Mac green staff.
There have been various flags on the Old Mac greens, as a number of flag styles have been considered.
Hope this helps,
Tom
ps...........heat wave on the coast; 80 degrees and windless!
