Here are some snippets from an article about Dion Jordan's performance in a game earlier this year- who wrote it? "Of the 17 snaps Jordan took, he dropped back to cover on four of them. Of the remaining 13 pass-rush snaps, I counted him pressuring the quarterback twice." "Jordan lined up on the inside of the offensive line formation on four of the above snaps. On three of those snaps, he dropped back into coverage. The fourth time lining up from the inside position with his hand off the ground, he spied on the quarterback." He also dropped back into coverage one time from a down position as a right defensive end. "The team also put all three starting linebackers—Dannell Ellerbe, Philip Wheeler and Koa Misi—on the field. It rotated dropping Misi or Jordan back into coverage while Wake and Vernon rushed, and at times linebackers Wheeler and Ellerbe would also blitz." "One should note that the above play was the only instance from which Dion Jordan dropped back into a coverage while the Dolphins were in one of their special personnel packages. The other three times he dropped back into coverage, the Dolphins had four defensive linemen on the field, including two defensive tackles." "With both Dion Jordan and linebacker Phil Wheeler pulled out into zone coverage to the left side of the offensive formation, the danger of a flatfooted quarterback such as Brandon Weeden recognizing the unbalanced rush and scrambling for yardage was minimal." "While this particular instance did not necessarily take full advantage of Dion Jordan’s rare agility and overall skill set" - I say let's make full use of that skill set. Sounds to me like Jordan has gotten some pretty good experience in pass coverage this year. As to Gronk, Jordan's experience in pass pro is in zone from what I've seen, I would expect the same if he were to cover Gronk, covering him in a short zone and releasing when Gronk goes deeper down the field, picked up by a DB, same sort of thing that the college tape shows.
