I don't want to take anything away from Miller. He was never (with the exception of maybe one or two games) a game changing back. Maybe that isn't fair to him because the line was garbage, or because we didn't use him enough. There were plenty of times we stopped using him because he kept getting tackled at the line of scrimmage. I remember most fans wanting Ajayi to take more snaps. Bottom line - if you are going to pay a running back that much money he should be your workhorse and you should want him on the field as much as possible. You shouldn't be wanting him to split carries.
