The Miami Herald says "there is a quiet confidence" at Dolphins camp that Lamar Miller is ready to break out.
Miller has been mentioned several times by GM Jeff Ireland as someone he expects to take a big step forward and is running with the Dolphins' first-team offense during OTAs. "He's just so smooth," QB Matt Moore said. "He's different from Reggie Bush but can get similar results. His nature is go north and south, Reggie's [style] was more to dance. He has grabbed the leadership reins."

Dolphins CB Brent Grimes (Achilles' surgery) is working with the first-team defense at OTAs.
Per the Miami Herald, Grimes is "looking fully recovered," despite getting beat on a deep bomb by Armon Binns. He's manning left corner with Richard Marshall stationed on the right. Rookie Jamar Taylor will compete for nickel duties once he's recovered from sports hernia surgery. The Dolphins will have more talent in their secondary this year, but the group is littered with question marks.

The Miami Herald "(keeps) hearing" rookie RB Mike Gillislee's name from Dolphins sources.
