Do agree with most of that, but for me Hilliard is someone I would keep, he can and does score goals.
Pepe should be given a chance to prove himself, looked a decent player before his injury.
Bishop is a worker and run's and chases all day long, and you don't find many like him.
The rest should be given the chance to prove themselves to the end of the season.
Roberts is another I would keep,we know what he can do and brings to the team.
