I've often wondered if Radagast had more of a hand in the story than we generally appreciate.

Specifically as a contact with The Eagles (and if eagles perhaps Manwe???)-

Bilbo & co at the fir trees, Battle of Five Armies, Gandalf's ecape from Orthanc and from Zirak Zigil, Battle of the Morannon, rescue of Frodo and Sam - so fairly influential I'd say.

Of course we can't really link any of these with Radagast except the escape from Orthanc, but I think it's a possibility.

So perhaps Radagast failed 'on points' ? His heart was in the right place but he just didn't get sufficiently involved with the fight against Sauron?
