Crew figuratively executed by skater (5)

I believe the answer is:

eight

I'm a little stuck... Click here to teach me more about this clue!

'crew' is the definition.
(an eight-person rowing team)

I cannot understand how the rest of the clue works.

(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" .)
