Crew figuratively executed by skater (5)
I believe the answer is:
eight
'crew' is the definition.
(an eight-person rowing team)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eight that I've seen before include "Number (of oarsmen?)" , "Mathematical cube" , "Crew of racing shell" , "One over it and you were drunk, it was said" , "Rowing boat crew" .)
