The elevation change into the 14th green is easily perceptible, but what you can's see from 125 yards out is how small the upper left tier is. Once you factor in how quickly a shot missed just right of the target will in the best case end up on a lower tier and in many cases end up all the way off the front of the green with that deep bunker in your face, an approach to the upper tier might be the most exacting shot on the entire course. In places like that, Pebble is a precursor to TPC Sawgrass before it was softened a bit. There are numerous shots that place you on a razor's edge with a severe penalty for missing the mark by a few feet. Winter conditioning and weather tends to reduce the danger of those shots for pros.
My biggest takeaway from the telecast is Cantlay's swing. I'm sure many have voiced this thought before, but his action looks like Elkington. Seemingly effortless power. It's surprising his 2013 back injury was golf-related as it looks like his swing puts little to no stress on his body. Of course, I'm not a swing coach or physiologist, but it's refreshing to watch a younger player who's not jumping out of his shoes.
