The Miami Dolphins are working on their preparations for Sunday's game against the Tennessee Titans and with a new coaching staff (more or less) comes the possibility of lineup changes.

A source tells me that although the team has not fully decided on changes and will monitor what happens at practice this week, there are indeed possible changes being considered at right guard and wide receiver.

I told you this morning I would bench Greg Jennings for DeVante Parker. The Dolphins are certainly considering benching Jennings. But his replacement would more likely be Kenny Stills instead of Parker.

Stills had the best game of any Miami receiver against the New York Jets, as he caught five passes for 81 yards and a touchdown. He had a 42-yard reception in that game.

The team is also going to look closely at putting Billy Turner at right guard ahead of Jamil Douglas, per a source.

Douglas, a rookie who has started all four games this season, has struggled so far. He is one of the lowest-graded guards in the NFL, according to ProFootballFocus.com.

So the Dolphins are going to consider returning Turner to the spot he held down at the start of training camp. Turner, whose reputation is of a physical player who still needs refinement, fits into the narrative new coach Dan Campbell has laid out for being a "nastier" team, particularly up front on the offensive line.

[Update: Interim coach Dan Campbell said Turner "worked in" with the starters at practice today.]

“Billy worked in today with the starters and we’re just going to see how he progresses this week and Jamil is working at it too," Campbell said. "We like both of those guys, they both deserve an opportunity to compete for the job and we’ll see what happens."
