Team runs to Plantagenet stronghold (7)

I believe the answer is:

rangers

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

'team' is the definition.
(Rangers F.C.)

I don't understand the rest of the clue.

(Other definitions for rangers that I've seen before include "Rovers (or > Wanderers?)" , "Scottish players" , "They look after the Forest" , "Administrators of Forest" , "footballers" .)
