No, having someone as a regular before they are well-rounded characters does not work. The interns/residents from season nine all became well-rounded characters in the second half of season ten. Too bad they already were main characters from the beginning of the season, because that made the writers kind of obligated to give them screen time, even though they had no interesting stories going on.
