I've seen Spudd a few times around my area over the years - once he was guest bartender at Pittwater RSL, downstairs in their old sports bar, one Saturday arvo/evening.
He's got a big personality, like a lot of other league players (I've got a theory that the elite league players were very active (possibly hyperactive) kids (hence big personalities that can tend to come across as loose cannons at times) who managed to channel their energy into sports) but I was a tad concerned when I went to the loo & he was at the urinal muttering to himself for quite a while.
I've noticed the same thing with Geoff Toovey (he was muttering to himself at one of the coin toss stalls, trying to win a bottle of port at a charity trivia night at my kids' old primary school) & Gene Ngamu (played a futsal comp some years ago where he was in one of the opposition teams & when I marked him I could hear him muttering to himself too).
I wonder if that's a symptom of concussion/CTE or if it's just a holdover of their playing days when they probably verbalised their thoughts out loud while on the field (nothing wrong with that, I find myself chatting to myself when doing manual work myself & I don't think I'm crazy lol).
