The underlined word is the complete subject.

A subject in the sentence refers to who performs an action. Whereas, a complete subject is also the simple subject or main word in a sentence which may have a modifier to describe it.

To identify a complete subject in the sentence, it answers to the question of "Who performs the action?" or "What performs the action?" A complete subject includes the subject and the words which modify it.

Therefore, in the above sentence, the subject 'Coach Mack's basketball team' is modified by 'from 2011.'

themselves

an intensive pronoun is a pronoun that ends in self or selves, such as himself, herself, themselves, yourself, ourselves. since band members is a third person plural, the correct intensive pronoun would be themselves. if the band was talked about as a collective noun, itself would be the appropriate intensive pronoun. intensive pronouns are used to add emphasis to the noun it's modifying which is why it directly follows it.
