The evolution of statistical analysis in sport has been rapid over the past few years and golf is very much included in that. The advent of the Strokes Gained metric has banished antiquated statistics such as putts per round and greens in regulation (GIR) to the history books.
The reason for that is the relatively poor information players could glean from the aforementioned categories. Simply counting your putts per round or GIR can be very misleading and is so heavily influenced by how close you hit your approach shots or how well you drive the ball respectively. For example, if you hit 18 greens in regulation on a given day, but all to over 40 feet from the hole, then 36 putts would be an exceptionally good day on the greens.
