linebackers

Looking at our linebackers right now is there a viable option to win now? Do we change there are of responsibility? Do play lansanah, casillas, fletcher, foster, magee?  How can we put players and process in place to win now? I know fletcher has got a bad rap from this board, but I don't see mason playing much better. Some have said move him to wsl. How can we get the best players in the best position?
