Big Sky Conference team (5)
I believe the answer is:
idaho
'big sky conference team' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for idaho that I've seen before include "US state, capital Boise" , "The Gem State, known for its potatoes" , "Northern US state" , "State of NW US" , "State of north-west USA" .)
