I think he's injured. Although I think somebody on here mentioned he was a bit of a Billy Big Bollocks, so maybe he was released.
Most are very young, we basically play kids in the youth and reserve games now, Oxley is the oldest(22), the others are 17-19, with the exception of Emerton, who I think is 20.
he's was sub last week for youth cup tie. seen quite a few youth team games over the last couple of years, JB never really fulfilled his potential and is a bit lazy in my opinion, when he signed, he was given a promise of a pro contract as part of his deal, which has probably held him back in the long run.
