One's not committed? Get an answer to this (4,5)
I believe the answer is:
free agent
'one's not committed?' is the definition.
I can't explain the remainder of the clue.
(Other definitions for free agent that I've seen before include "One acting without constraint" , "Nobody can force me" , "He is not bound" , "One unrestrained" , "who would be a gift to any actor seeking work?" .)
