Team's affectation (4)
I believe the answer is:
side
I believe this is a double definition.
'team's' is the first definition.
(I've seen this before)
'affectation' is the second definition.
(I've seen this before)
(Other definitions for side that I've seen before include "Spin given to a ball by striking it off-centre" , "Sporting team" , "Competing players" , "Pomposity - bias - team" , "Face - team" .)
