While DeSean Jackson is getting older, he’s not showing many signs of losing his ability as a deep threat, at least in my eyes. The problem is more that Jackson and Kirk Cousins have struggled to get on the same page at times this season.
The story breaks down some of Jackson's routes and mostly puts the blame on Cousins. The author thinks maybe the team tries to find more ways to get Jackson the ball in the second half, as he's averaging less than four catches a game this year. Jackson has usually been a boom or bust play through much of his career which makes him a risky fantasy play most weeks as anything but a WR3 or lower.
