I don't see why everyone is so surprised Rex is having thess issues. I think he is a wonderful QB but he needs experience. Despite it being his 4th year, this is basically his rookie season, due to all of his previous injuries. Give him time, if he doesn't get better with experience (by mid next season at least) then bench him. If they go to Griese yes, they will win right now but they will have to find another franchise QB and go through the "experience" again.
