Please explain the function of the verb "do" and "were" in stead of pointing out the Idiom format..

were playing
were is an auxiliary verb.
playing is the action verb.

do replaces action verbs only.

john has read more than i have.
the auxiliary verb must be repeated and do cannot replace the verb here.
