No.
Carney will just cause more headache for the club. When the whole Northies shit came out, so did all the small incidents Cronulla swept under the carpet; being banned from club and social events, being sent home from training etc. Same stuff that happened at Canberra, same stuff that happened at the Roosters and I doubt anything would have changed in the UK. The club is better off finding another half in the NRL, in the ESL or backing Cogger and Lamb.
Carney simply doesn't fit what we're trying to build.
