I am hoping it is Washington at FS. If we put Bonner back there, especially a hobbled Bonner, against THIS team, we are toast. We need speed on the field, especially at FS. And we need sure tacklers at Safety to handle their dink and dunk stuff. Bonner has shown me neither.
Hell, where is Marvin Bure? He showed out in the spring game and scrimmages supposedly and is supposed to be one of the fastest players on the team.
Anyway, to answer the question, I think in nickel packages you will see Washington slide over and Watson/Anderson man the corners. Whether it is Banks or Bonner at FS, I do not know.
I say keep Bonner at nickel and rotate Banks, move Washington to FS and let Watson and Anderson handle the corners (unless Banks is better there, too). It ain't pretty, but it might be the best we can do.
