Reynolds graduated from a 10-game NRL rookie to a future NSW Origin bolter in 2012 after his superb form guided the Bulldogs to the grand final.

Kimmorley played an influential role in the development of Reynolds and partner Kris Keating as a specialist halves coach at Canterbury this year. And Williams is excited by the prospect of Kimmorley, the new Raiders assistant, overseeing Canberra's batch of promising young halves.

''Last year he was a bit more of a specialised halves coach, so he obviously worked pretty closely with those guys,'' Williams said on Tuesday.

''What they [Canterbury] did last year was a combined effort through the whole team, but what the halves did off the back of it was really good.

''They [Reynolds and Keating] are different styles of footballers, but it does give you confidence.''

Kimmorley and the promotion of last year's Toyota Cup coach Andrew Dunemann to NRL assistant means Williams will now be nurtured by two former halfbacks.

Former assistant Andrew McFadden also had a long career in the No. 7 jersey, but has moved to the Warriors for next season.

''We spent a couple of years there with 'Cappy' [McFadden], another half who played first grade, and another couple of halves here will bring fresh ideas and change some things we do,'' Williams said.

Williams joined teammates Josh Dugan, Joel Thompson, Brett White and Tom Learoyd-Lahrs in spreading some Christmas cheer at Canberra Hospital's Ronald McDonald House on Tuesday.

All Williams wants for Christmas is to cement his place in Canberra's starting line-up after he was the Raiders' standout in last season's finals series.

''You take a lot of confidence out of those games. Playing well on the big stage is important and a lot of people notice you there,'' he said.

''I just want to take that form into the trials and if we play like we did at the back end of this year, we should be pretty dangerous.''
