Mathew Stafford has had a RB run for 100 yards exactly 7 times.

Most teams do that every year.

It is time to make RB the top priority.

This is AA's make or break year. If he can stay relatively healthy for the year and runs like he did at the start of last season, they will have their RB. If he doesn't work out then it will just be a priority next off season. Quinn has smartly built his line first and is giving the players on the roster a shot.
