#Packers DT BJ Raji has tests today on his upper arm he injured last night. He was optimistic last night. But not a lot of optimism now.

#Packers DT BJ Raji, playing on a one-year deal, had drawn rave reviews in camp back at his natural NT position. Now it's all in doubt.

Rapoport, I have guessed earlier, seems tied into David Dunn (Rodgers, Matthews, Raji's agent). And I think that explains his good information about all three contracts for these guys and his correct call on rebuilding the D line.

If someone was to know before M3 knows, its probably Rap Sheet.
