Based on his development and play last year, James Sanders has earned the starting position at SS. Having a Safety crew, purposely not counting Rodney, of Wilson and Sanders with Meriwether and Hawkins and then Chad Scott and Willie Andrews as a Safety corps is really pretty solid. One near pro bowler, and at least three competent players. Rodney is on the downside and everyone knows it, except the fans.
This is Rodney's transition to key reserve from starter status. And the pay to go with it. Fans did not think that Rodney had a replacement, but he does. Teh Pats coaches had to play sophomore Sanders nad he got blooded. The Fans were forced to confront that fact that Bruschi has a replacement, as Vrabel moved inside and took over his job, the year Bruschi recovered.
No Team is forever, other dynasties died because the starters got old. In the Pats case, the Team has consistently transitioned older players, and replaced them. And gotten younger while remaining strong.
The only starter older than 30 on the Offense is Stephen Neal who will turn 31. The only starters older than 30 on the Defense are Bruschi, Vrabel and maybe Harrison. Both Bruschi and Harrison have players groomed to take their places. Vrabel will turn 32, so he should have a couple more years as a starter.
In this respect Rodney joins the quality depth of ex-starter quality veterans, who maybe can't do it for 60 minutes for 16 games any longer, but are great players who can still produce in spurts, Guys like Scott, Hawkins, Junior, and maybe Tory and Vinny.
