The Miami Herald's Barry Jackson is back with some Dolphins buzz. Highlights of his piece include: -Dolphins concerned with Brian Hartline's "focus and consistency." Like most fans, the team is reportedly "disappointed" in him thus far. -Why was Lionel Dotson brought back rather than one of the two vets the team cut? The team reportedly thinks he progressed a lot in camp and the team wants to continue getting younger. -Jason Allen is playing better because of Mike Nolan's system, according to Jason himself.
