I haven't heard any stories about him going mental with the nightlife. The impression I get is that he's one of those fellas that people love to hate - he's clearly a smartass. I've been managing people for years (granted their techheads) - but, if i'm deducing his character correctly, they're the type i'd want to get rid of as soon as HR-ally possible as they're Basically, smart-alec arseholes. Most important to note, they are pure-poison in a team.
I hope i've completely read him wrong and even if not, it's easily coachable, but needs a solid mentor.
Stokes ,in my view. is a fella that wants to be half-a-gangster. He's got the full whack: violence, sex tapes, the Reals etc.To that end I would argue that's got some serious psychological issues and was never going to change unless he underwent some major therapy (I mean this in a genuine way)
I wouldn't put Gibson anywhere near these two. He was doing grand for the most part until he did his cruciat. That's when it looks like he started hitting the bottle. We should all be rooting for him imo. He always seemed to be a moody gruagach but there's not too much plamas from him before 2014.
