Still among the best at ice hockey (6)
I believe the answer is:
static
'still' is the definition.
(static can mean still or not moving)
'among the best at ice hockey' is the wordplay.
'among' says the answer is hidden in the clue.
'STATIC' is hidden within 'best at ice hockey'.
(Other definitions for static that I've seen before include "showing no signs of going anywhere" , "Still - radio interference" , "8-ing - sort of electricity, line or memory" , "Motionless like some kind of electricity" , "Crakling or hissing noise caused by electrical interference" .)
