Start with the quarterback position. Jay Fiedler will get the start against the Bucs, but he won't play that long because the coaching staff wants to take a longer look at A.J. Feeley to see if he deserves to supplant Fiedler.
Then there's the offensive line, where the Dolphins still are looking for the right combination.
The starting line against Tampa will consist of Wade Smith, Jeno James, Seth McKinney, Taylor Whitley and John St. Clair, but the Dolphins also want to take long looks at guys like draft picks Vernon Carey and Rex Hadnot.
Edwards is expected to start against Tampa Bay.
The Dolphins also want to find themselves solid kick returners, and newcomer Terrence Wilkins gets his big chance tonight. He's missed a lot of practice time because of a hamstring injury, and if he doesn't shine Saturday night, we're thinking he's done.
He will split time on kickoff returns with Fred Russell and on punt returns with Sam Simmons.
Lastly, this game is a last chance for several youngsters to show the coaches they should be kept ... at least until the final cuts.
Among those who will really need to shine if they get the chance are RB Renaldo Works, FB Ben Moa, WR Carl Morris, TE Hart Turner, T Tony Pape, DT Jerome Stevens, DE Josh Mallard, LBs Winston Taylor and Brenden Givan, and DBs Kevin Millhouse and Todd Howard.
