How teams play? Rather! (8)
I believe the answer is:
somewhat
'rather' is the definition.
(thesaurus)
'how teams play?' is the wordplay.
'play?' is an anagram indicator (I've seen 'play' mean this).
'how'+'teams'='howteams'
'howteams' anagrammed gives 'SOMEWHAT'.
(Other definitions for somewhat that I've seen before include "Quite" , "To an extent, a little" , "Moderately" , "To a certain extent" , "To a small or moderate degree" .)
