I think thats more of the case point really. Evans has done his time, regardless of if he's admitted guilt. Ranger hasn't served his time, well he has in youth offending and there has been no change to his behaviour and attitude. Two different cases. Myself I only believe in rehabilitation once a person admits guilt and feels guilt. Thats a whole different debate though and far away from football.
If you don't like his attitude or behaviour then don't employ him. I personally think Blackpool are fools for taking him on and it'll bite them in the ass but it's their decision.
