The Jaguars added LSU WR D.J. Chark with the 61st overall pick of the 2018 NFL Draft. Chark’s stock got a big boost when he ran a 4.34-second 40-yard dash at the Combine. He also posted 90th+ percentile marks in the broad and vertical jumps, earning a SPARQ score in the 96th percentile. Chark didn’t post huge numbers at LSU. He went without a single catch in his first 2 seasons before a 26-466-3 line in 2016. This past year brought a quasi-breakout, with Chark hauling in 40 balls for 874 yards and 3 scores. His 21.9 yards per catch led the entire country among players with 40+ receptions. It’s certainly worth noting that Chark played on a bad LSU passing game. He accounted for 22.3% of the catches, 33.0% of the yards and 17.6% of the TDs last year. And his 2.92 yards per route run ranked 12th among draft-eligible receivers, per Pro Football Focus. Chark at least looks like a guy who can bring big-play ability to Jacksonville. But he’ll need to refine the other parts of his game — notably his route running and hands — if he wants to turn into more than a boom-or-bust fantasy option. Chark joins a crowded Jaguars WR group that also includes Marqise Lee, Dede Westbrook, Donte Moncrief and Keelan Cole.
