 First round draft choices such as running backs Joe Don Looney, Tucker Frederickson, and Rocky Thompson were disappointments.Frederickson was selected as the first overall draft choice in 1965 (over Hall of Famers Dick Butkus and Gale Sayers), but never rushed for more than 659 yards in a season during his injury-shortened career.This period in team history is often referred to as "the wilderness years".
