They weren't ghost routes, they were reads by Drew Brees. If the corners are in coverage and the safety is over the top, you don't throw the deep ball, you throw to the middle of the field where there is a hole in the zone. Brees could still make those throws in 2016, Cooks was mad he wasn't getting the ball enough. He still had like 117 targets. But CGM and Willie Snead also both had over 100 targets. Plus Fleener got 80.
