Last year Damion Square and Robert Lester signed with team as free agents and both ended up as starters at one point or another. I think Hubbard and Mandell will both end up on the active rosters for their teams next year. Of the later round guys I think Pagan is in the best situation. He gets to play with the best D-Lineman in the league, JJ Watt, and will not be pressured to perform right away like Clowney will. I think Stinson is gonna end up starting in AZ and will be one of those guys that has a job for years and years that doesnt get much praise publicly but is one of the more consistent players.
Of the earlier guys I think Mosley is in the best situation, yes he will get compared to Ray Lewis at every turn but he's playing behind a massive D-Line that includes Cody and Ngata and also play with his buddy Courtney Upsahw (who by the way Harbaugh and the D-coaches in Baltimore called the most underrated player on their team).
