Patton certainly isn't the answer to your problems. He's had plenty of chance to show his worth at the Wire (he was starting half back for much of the season when Kev Brown was injured) and he's failed to deliver. His best role has been as impact hooker.
I know that quality half backs are in short supply (we've had a problem with our recruitment for a number of seasons) but I just don't see Dec as being SL standard. If you want him then there are plenty of Wire fans who would be more than happy to offer him a lift over to your place.
