Strengths: Marlon is a very athletic wide receiver with great size. He possesses good open field speed to pull away. He is the type of receiver who obviously can go up and catch a fade route, but he also shows the ability to take a short pass like a hitch, slant, or quick and turn it into a homerun. The video shows that Marlon has great hands and concentration to make a catch in traffic. He shows great vision on the inside screen routes. Notice how he is able to find the open field and follow the screen lane. His willingness to go across the middle and focus on the catch is good.
Areas to improve: Although there are times he is able to make great moves to avoid tackles he has moments where he could work on ball security. He does display the ability to keep the ball tight to his body. There are times when he makes his moves by bringing a high lift over his opponent and can leave the ball vulnerable. He has great moves, but will need to improve his route running for the next level.
