If he was given a chance on a reasonable deal for one year with a second year option I'd be happy enough.
Probably would only feature in half our games, not unlike Gidley. But would still make a valid contribution and Patton would be getting game time.
There's certainly a lot of entertainment value to be had from Carney and he's a proven match-winner. Bearing in mind there's not much else on offer we could do worse than give him a chance... expect the worse, nothing more and maybe we'll be pleasantly surprised.
