Giving autographs, player team has acquired (7)
I believe the answer is:
signing
'giving' is the definition.
The answer and definition can be both to do with communicating as well as being present participle verbs.
Perhaps there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for signing that I've seen before include "recent addition to team" , "Writing" , "Autographing" , "means of communication?" .)
