Jalin Marshall was an off-season star. He was singled out for praise by players and coaches and even beat reporters were waxing poetic about him through training camp. He was making plays and opening eyes, not only could he contribute on special teams, but maybe he could contribute as a wide receiver straight off the bat.
Marshall decided to leave Ohio State with two years of eligibility remaining. Although he had solid production while in Columbus, he went undrafted last year. Many scouts believed he was the product of a pro-receiver system in Ohio, that he didn't have the acceleration or the catching ability to be a good pro. Some said his release was poor and he'd struggle to beat press coverage in the pro's.
During his first year in New York, Marshall finished with 14 receptions for 162 yards and a 2 TD's. He was targeted 23 times, meaning his catch % was above 60%. He returned 13 kicks for 324 yards (24.9 yard average) and returned 18 punts for 100 yards (5.6 yard average).
Consistency was the key for Marshall, he went through a couple of games where he put the ball on the ground with some costly fumbles (3 in total through 2016) and a shoulder injury sidelined him early. He obviously has talent, but after breaking camp with the Jets as the number 4 receiver, I think it's pretty clear that Robby Anderson is the clear number 4 as things stand.
The concerns in relation to Marshall coming out of college still stand. He does need to add some hand strength to get off the line a little quicker. He does need to continue to work on his route running and ball protection. However he can help you in several facets of the game. He'll definitely be fighting for his roster spot in the summer, but he has a base that he can build on with the experience he gained with the Jets in 2016.
