from the article:
"At just under $600k per year, Matthews’ salary is very team-friendly. Should the Dolphins retain Gibson, Wallace, and Hartline, Matthews should still have a place cemented on the roster thanks to his production and the low cost of keeping him. Even if he’s forced into a diminished role on the offense, he made a positive contribution to the team, something most seventh-round picks can’t claim. Snaps may be very hard to come by, so it will be up to Matthews to seize every opportunity if he’s to hope for more playing time.
Whether or not Matthews is in the Dolphins’ long-term plans may not be up to him. They currently have three receivers on the roster signed through 2017 and that’s not counting the deal Landry will sign in the upcoming months. With so much money committed to the position, it’s hard to envision Miami looking to shell over more to Matthews when he becomes an unrestricted free agent in 2016 without first releasing some of the high-priced wideouts ahead of him on the depth chart. It will be interesting to see whether Matthews can take that next step and break into the starting role, but he certainly has his work cut out for him."
Doesn't sound like a super star to me just a good value for a 7th rounder. I hope he has a good year but his up side is no where near that of my pick Jordan.
