The group will be bolstered this evening by the presence of newcomer Antonio Freeman, who is expected to play about a dozen plays.
He'll be one to watch as well.
The offensive line also will be under the microscope after all the changes Coach Dave Wannstedt made earlier in the week.
To refresh your memory, first-round pick Vernon Carey went from tackle to guard, Greg Jerman went from first-team right guard to second-team right tackle, Billy Yates went from backup left guard to backup center, and rookie Rex Hadnot went from backup center to backup left guard.
The guy to watch here obviously is Carey, whom the Dolphins obviously would like to see in the starting lineup.
But it's Taylor Whitley who will get the start at right guard against Washington.
At running back, the guy to watch will be Fred Russell, who will get more carries tonight with Sammy Morris out with a concussion.
Finally, there's the kick returning, where the Dolphins still are looking for someone to step up. Russell had a nick kickoff return last week and he'll be given another look.
