I wasn't a fan of the idea of Prem teams entering. It just seems like the Premier League bullying their way into getting something they want. Eventually they'll bully their way into having b teams in the lower leagues.
There's better ways of developing youth players and giving them experience such as loan moves or even giving them chances within the first team.
Last season we had several youngsters or squad options come through and contribute. Kevin Stewart was probably destined to get released yet came into the team, did a job for us and has been given a new contract.
