A bit split on this one.
On one hand, the idea of a convicted rapist going back into a profession where he can do really well for himself and almost get away with what he did now he's done his time seems unfair and poor.
But, on the other hand, once criminals are released, they're going to have to earn a wage like everyone else. In that sense, he's perfectly entitled to return to football since that happens to be how he earns a living, and any club is entitled to hire him. He'll be at an automatic disadvantage in that clubs who'd have been happy to buy him will now be more reluctant because of the stigma attached.
