These will change.
Last year the D ratings by position were:
DL: Daniels: 83, Wynn 79, Griffin 87, Noble 75
LB: Arrington: 97, Barrow: 90, Washington 89
CB: Springs: 89, Harris: 78
S: Taylor: 85, Bowen: 79, Clark: 69, Lott: 65
I imagine that Griffin, Washington, Springs, Taylor & Clark will all go up. Taylor had like a 55 awareness rating last year.

ey was a 69 overall and I'm sure he'll go up.
Players we added: Holdman: 86, Patten: 78, Rabach: 83, Moss: 89.
I can see Patten & Rabach going up. Patten was injured the previous year but led the Pats in TD's and held the highest YPC last year. Rabach played the entire year for Flynn who was injured but still started after Flynn came back.
I wouldn't worry about these ratings quite yet. When IGN posts them in late July early August and our D is still rated that low... then I would start to worry. It also had Blache as our D Coor. Hopefully they put GW in this year.
