Bear name of rugby forward (6)

I believe the answer is:
rupert
'bear name' is the definition.
'rupert' can be an answer for 'bear' (fictional bear Rupert the Bear). I am unsure of the 'name' bit.
'rugby forward' is the wordplay.
'rugby' becomes 'RU'.
'forward' becomes 'pert' (both can mean cheeky or disrespectful).
'ru'+'pert'='RUPERT'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for rupert that I've seen before include "Poet who wrote of ..." , "It's bought unseen (1,3,2,1,4)" , "Comic strip bear" , "Prince" , "chap" .)
