5. Patrick Chung, S
Chung was not a Pro Football Focus favorite in 2010, in part because of a number of tough losses in coverage. Chung’s job is difficult, with so many responsibilities. He’s too small to play linebacker, but he’ll crowd the line of scrimmage anyway as if he was one. He’s also much smaller than the tight ends he covers, but that’s the nature of his position. But he looked like he couldn’t quite keep pace in coverage, even though his run-stopping duties continued to be solid. New England may have added veteran Adrian Phillips and rookie Kyle Dugger, a second-round pick, as contingency plans, if Chung can’t improve. And though he’s 32 years old, Chung should be fine in 2020 with an offseason to heal and refocus on the fundamentals.
