Even though he's been a complete idiot, I don't see why we wouldn't go ahead with his signing.
Stooke has faced significant penalty:
3 match ban
14 month driving ban
Fines of £2,562.
He faces damage to his reputation, potentially misses out on a final pay day abroad (Cipriani had to turn down a big money deal in Japan due to his drink driving conviction) and higher insurance premiums when he gets his license back.
If he has already signed a deal with us, I'm not sure we could cancel his contract without having to pay him compensation, as he wasn't a Wasps employee at the time of the offence, but one of our employees was with him for part of the car journey and may well have been a contributing factor in him breaking the law. Most likely we'd incur significant legal fees and possibly paying out the full amount of his contract if he can't find another club.
We've also employed Joe Carlisle after he was banned for 20 months having been caught more over the limit than Stooke was on his way to training and, most famously, Cipriani, who hardly put up a credible defence.
Most crucially, if we cancel the deal, who do we bring in to replace him at this late stage?
