Think the Doggies have denied it but Ma'a Nonu to the Bulldogs is the latest rumour doing the rounds. Frank Pritchard actually said it was happening on twitter a few days ago, the same day Nonu had been training with the Doggies!! Think some of the Kiwi press have picked up the rumour as well.
I think he'd do well in league, hes just turned 30 and having just won the RWC theres not much left to achieve in union I guess, perhaps hes after a new challenge and a big pay day no doubt.
