look in all honestly its probably just a culmination of things, and its hardly surprising tbh.
2015 he has a breakout year
gets his gf pregnant in 2016 sometime but they both know their relationship isn’t going well
2016 form suffers as a result, but they win premiership regardless
2017 relationship suffers total breakdown, form suffers even more, not helped by the fact the team is going poorly
ends up breaking up with girlfriend, goes on an end of season bender to help himself get over it (seriously wouldn’t hold that against him)
gets crucified at end of year review, im going to speculate and suggest the coach was insensitive to stringers off field struggles, he cracks the shits and requests a trade
I dunno, all the talk is a bit disconcerting, but it might just be a bit of an exaggeration
