• Offensive line: None of the rookies has duplicated the success of Samuda, who claimed a roster spot as an undrafted rookie last summer and now is working with the starters at right guard. Asked who impressed him among the young linemen Sunday night, Philbin could not name anyone.
Jeff Adams, Chris Barker, Chandler Burden, Sam Brenner or Jeff Braun will need to demonstrate a lot more to avoid the waiver wire.
• Linebackers: Undrafted Lee Robinson, 26, already has had stints with four NFL teams and the CFL’s Edmonton Eskimos and has made several good plays over the past three months. But he’s facing heavy competition (Austin Spitler, Josh Kaddu, Jonathan Freeny and others) for one or two jobs behind the three starters and top backup Jason Trusnik and fourth-round rookie Jelani Jenkins.
• Defensive backs: Undrafted safety Kelcie McCray, who spent all of last season on the Dolphins’ injured list, has had a good camp and appears to have a strong grasp on the No.4 safety job.
• Defensive lineman: Tristan Okpalaugo, an undrafted rookie from Fresno State, forced a fumble against Dallas, and A.J. Francis (who wants to be governor of Maryland someday) also has had his moments in camp. But it’s difficult to see any of five undrafted long shots at this position making the 53-man roster, largely because two second-year linemen, Kheeston Randall and Derrick Shelby, have played well.
Randall, a seventh-round pick in 2012, tipped an interception in practice Wednesday. Shelby had two sacks Sunday and “is a very, very sound player,” Philbin said. “I love him because … he gives effort, he’s in the spots where he’s supposed to be.”
