Like most, I was shocked regarding Jalin's decision to leave early after this past season.  But like all (I'd hope), I'm rooting as hard as I can to see him make an NFL roster.  Sounds like he's doing what he needs to so far.

Through five practices, Marshall has made a positive impression. He looked like an intriguing prospect in spring practices, after the Jets signed him as an undrafted free agent out of Ohio State. Now, he is pushing to make the team. 

Marshall would factor in primarily as a punt returner. He returned punts the past two seasons at Ohio State. But with second-year receiver Devin Smith still recovering from a torn ACL that he sustained in December, there likely will be an extra receiver spot available on the Jets' Week 1 roster. 

 And get well soon, Devin.
