Andrew Wilbar: The first thing that pops out with Johnston is his athleticism. Johnston does an excellent job using his combination of size and speed to get downfield and win on 50/50 balls. He possesses outstanding body control, leaping over and around defenders to make catches while still maintaining balance and staying on his feet to make something happen after the catch. This true acrobatic ability is also a benefit on third downs, as Johnston does a great job of keeping his feet in bounds and maintaining forward momentum to move the chains on passes near the line to gain. The most talked about issue with Quentin is his hands. He struggled with drops throughout his collegiate career, many of which are due to poor concentration. He often turns his head upfield before securing the catch, and his hand positioning is the slightest bit off at times. Johnston also needs to cut back on the body catches and trust his hands more. Another concern I have with Johnston is his lack of speed at the beginning of his route. He does not have a great first step off the line, and it sometimes takes him a couple steps to really accelerate. I am also not impressed with his physicality as a run blocker. Ultimately, I see Johnston as one of the bigger boom-or-bust prospects at the wide receiver position. However, the risk may be worth it, as his physical abilities are among the best in the class.
