Ja'Lynn Polk has an ideal build for the position, very long and slender, however, he is not an elite athlete. Although he is a fluid athlete, he tends to play too high on his footwork and lacks the speed to consistently attack the third level deep or elite acceleration. He can generate explosiveness but not consistently. He has excellent body control and a naturally strong grip, which is very promising. However, in terms of his playing style, he lacks power, but it would be challenging for him to gain muscle mass without further affecting his athleticism.

His release repertoire is decent, but his footwork lacks explosiveness, and he needs to better understand how to use tempo to create more uncertainty and surprises for the cornerback. In press coverage, he struggles to assert himself physically on the line of scrimmage. I've seen him get jammed by good cornerbacks, and they didn't have much trouble mirroring Polk's release. His ability to create separation is limited due to his tendency to run upright, his lack of use of arms, and his lack of elite athleticism. He lacks quickness and consistency in his footwork. The best of his game comes against Off-Man coverage and zone coverage. When he has space to build up speed and execute his plays, he is much more dangerous.

He has a fairly well-developed route tree, but there is still room for improvement. He has the ability to develop his vertical routes both inside and outside and has already shown some flashes during the season. Ja'Lynn possesses good hip fluidity, allowing him to make smooth changes of direction on long routes (although his footwork in this area is not optimal yet). He can create separation with head and shoulder fakes. His breaks aren't lethal, and although he still needs to work on his timing, they are generally well executed.  He has a good IQ against zone coverage, his crossing routes are surgical, and he knows when and where to sit in his route to provide a viable option for his QB, but he still needs to work on creating separation. 

Ja'Lynn's ball skills are elite. He has long arms and a significant catch radius. His ball tracking is excellent, and his eye-foot-hand coordination and ability to adjust to throws are elite. He has the best hands in the draft class. His technique is excellent, and his ability to attack the ball at its highest point is impressive. His excellent ball security is the first thing that jumps out to me in this group of wide receivers. His ability to win 50/50 balls and turn them into 80/20 situations or make acrobatic catches is really strong. He has a very smooth transition from receiver to runner, and even though he's not an excellent athlete, he has sufficient agility to gain yards after the catch.

Polk's run blocking is very average; he gets overpowered physically and lacks consistency in technique. His lack of enthusiasm is evident, and his performance fluctuates too much.

Ja'Lynn Polk is one of my favorite prospects in this draft, his elite ball skills are truly impressive, and I really like what he brings in the slot. He has genuine versatility. I envision him as a strong No. 2 option in an offense with rotational usage in the slot to keep defenses guessing. He lacks the athletic prowess to be a primary No. 1 receiver in the NFL and fits more as a possession receiver.
I assess Ja'Lynn Polk as a second-round prospect.
