I know this thread is about Rory's putting but Spieth is definitely not a poor driver of the ball
Compared to Rory his is, which was my point.
Going by pga stats. Rory has pretty much always had a better strokes gained from the tee compared to Spieth, in fact by a bigger margin than Spieths putting exceeds Rory’s.
But it was more just an comparison of the perceived strengths.
Although for me, Spieths biggest advantage is his grit.
