Assume he'll do a Reverse Abendanon, ie in France he's a world beater, at fullback at the Rec a good but limited player who no one seriously considers England material.
To be honest he sounds like another big money signing in a position we don't need. As does Steffon. Are we really turning into the rugby equivalent of a loud arsehole in an expensive suit lighting his cigar off burning £20 note in a bar in the City? Joy
Delon the Felon might be many things, but short of England material isn't one of them. If he'd kept his head screwed on, he might still be England's full-back.
And at the age of 32, his acquisition wouldn't be a long-term judgement of anything (particularly when he can play wing or even 13 himself).
Personality and cost aside, I wouldn't mind being linked with D Armitage.
As for Steflon - played 8 for Toulon enough, right? You could certainly fit him and Louw into the same back row.
