Receivers
DJ Chark, LSU: Chark's blazing 4.34 40 time impressed Mayock, but after he smoothly caught passes in the gauntlet drill, Mayock really liked what he saw: "He had a real good Senior Bowl week and he's coming out and competing today."
Looks like he is having a solid combine. Watching his highlights it looks like the kid tracks the ball very well.
