The latter half of the year has been a struggle for Rory McIlroy, and those issues were once again evident last week at the CJ Cup. McIlroy was tremendous off the tee but struggled mightily with his irons, losing 3.8 strokes on approach for the tournament. It was the second time in his last three starts that he's lost strokes to the field with his irons. He'll need to fix the issue quickly as he heads to the ZOZO Championship and a Sherwood Country Club layout that can be classified as a second-shot golf course. Tournament-winning upside is always present with McIlroy, but his spotty iron play as of late lowers his DFS floor.
