I'm not sure the pro Evans lobby (which includes me) are advocating we immediately rush out to sign him. I think what we are saying, and obviously I can't speak for others, is that, if those responsible for what goes on the pitch every week deem he would be an improvement on what we have them they should be allowed to make the effort to sign him.
I felt the same last year when ha had served the punishment laid down on conviction, it's perhaps not terribly surprising that I feel the same now that conviction has been quashed.
