This could be a series called FALLEN HERO
He was getting shunned by the sporting community for 'what he did' (can't remember) but just as he was going to crack with the pressure he won the pools!
Rest of series was about his family problems and his club realising that now they really needed him but he wasn't bothered cos of his cash
I remember him staggering drunk over the rugby pitch in middle of the night while clapping and chanting "Gareth, Gareth" so that must have been his name (Welsh accent?)
