You could tell as soon as he came into grade that this sort of stuff was going to happen, even without knowing the guy. He had 'I'm so great' written all over him but didn't have the next level talent to justify it.
I remember a try the Roosters scored in a drubbing of Souths (?) in his first year, where he threw a piss poor ball to Pearce who soccer kicked it through to score. Hastings performed like he'd just won the GF with a 75m field goal, running around taunting the crowd, pulling the fingers etc.
It's sad though, I know he's sought professional help in the past for how he deals with all of this.
Agree almost every time I saw him I thought the kid doesn't have what it takes attitude wise, the talent level may be debatable but he just looked like a little prick on the field all the time.
