Riviera is a great old fashioned course. It really reminded me of Australian courses with the kikuyu fairways and the smaller greens and guarding bunkers on some doglegs and around the greens. Allenby won there one year. Elk won the PGA there...even a hack like me had a 5th and a 10th there in the event when it was called The Nissan Open back in late 90's early 00's. So it was a great looking course for the Aussie's and fitted our eye well.
I honestly don't think the greens are that severe there. Not ridiculously filled with humps and hollows....although one green has a bunker dead smack in the middle of the green.

A few of the greens like #2 and #9 get a bit quick because those greens are built sort of into the hill at the base of the clubhouse area,so the hill dictates some back to front slope on those but certainly nothing crazy whatsoever. The greens are narrower in width than the majority of PGA courses, but still plenty of grass to hit at.
A few holes were lengthened from the time I first played there to the last time I played there such as holes 9 and 12 were lengthened significantly and Hole 6 (the par 3 with the bunker in the middle of the green) was pushed back 25-30 yards....but I haven't been there for a few years now but I don't think they could have altered it much as they had no real estate left to drop and tees back any farther. The 8th hole looks weird. It used to be a split fairway par 4 with trees ...so you could play left fairway or right fairway...now it looks like they ripped all the trees out and put a few fairway bunkers in. That old 8th hole was so tight from the tee, it was magic...position and then approach....I bet the guy who designed the course originally would have a cow looking at that hole now.
I think the fact that precision more than power may be finding a few guys out. The greens are not that small....smaller than your TPC elephant burial ground greens but hey- the greens are there ready to be hit, sounds like the commentators are making excuses for some sloppy play
