PROS: Good ability to track the deep ball down the field. Has a long catch radius and does well to snag balls away from his frame. Will attack ball late to prevent cornerback from making a last-second play. Great spatial awareness to make sideline grabs, as well as instantly transition from receiver to runner and make first closing man miss.
Has long strides that can generate some good short-area vertical burst, though long speed isn't particularly impressive. Can use length to assist in battles against physicality, especially when clearing throwing window on stop routes/comebacks. Shows the ability to work basic moves to release at line of scrimmage and at the break point; jabs and stutters primarily, with some head fake work. Has nice stop-start ability with hip drop. Will wipe hands to keep cylinder clear when working route stem, but timing and strength displayed are inconsistent.
CONS: Does not generate distinct plans for various types of coverage. Will get bullied by press within the contact window and lose the red line on vertical stems; lacks the short-area quickness to move off-coverage defenders off of their leverage. Ability to uncover highly reliant on cornerback technique relative to route--not on Vaughns' own ability/technique. Route tree limited to the vertical tree--stop route, comeback/quasi-speed out, and go route.
Despite good spatial awareness re: sideline play and YAC, a worrisome inability to bend/adjust routes into space is prevalent on tape, especially on in/out-breaking routes. Step frequency is low and breaks often require a slight lean, though he can do well to snap his shoulders to his QB and preserve momentum--the lean is just a big tip for the defender. Not agile and thereby not overly elusive. Frame is slight and gangling, leading to an aversion to physical play--especially egregious in reps in which leverage is needed downfield. Not a high effort player.
