NBC aired all but one stroke from winner Henrik Stenson (skipping a tap-in on 12th) and all but two from runner-up Phil Mickelson (bypassing tap-ins on #2 and #5). With those two separating themselves from the field, NBC focused heavily on that pairing. In fact, NBC devoted a whopping 56% of all televised strokes during this period to the Stenson/Mickelson duo (who didn't even tee off until 35 minutes into the tracking).
NBC televised only 224 shots during this period which worked out to 0.83 strokes per minute. This was a sizable decrease from the ESPN shot rate of 1.23 that I measured from the 2015 Open Championship and the lowest rate for any major that I have tracked. The lack of competition from the rest of the field clearly contributed to the low rate. NBC chose to aggressively spotlight the drama and excellence of the lead group (and take numerous commercial breaks) rather than fill time with relatively meaningless golf action from the rest of the pack.
For comparison, refer to the shot tracking data I compiled for CBS from the 2016 Masters and Fox from the 2016 US Open, In that Masters post, you can find links to the shot charts I did for the 2014 and 2015 majors.
NBC showed a total of 24 golfers during the tracking period. The highest finisher not shown during this span was Soren Kjeldsen who tied for 9th.
Here is the complete shot chart:
|Phil Mickelson||63 (of 65)||2||1|
|Henrik Stenson||62 (of 63)||1||1|
|Rafa Cabrera Bella||1||T39||16|
Note: The Pairing column reflects the tee time groupings in reverse order, so 1 = final pairing, 2 = next-to-last, etc.
