For me I would want to get past the Crappy's 'ball security's mantra. Yeah silly errors hurt us but this season we are pretty high on completions but look no better for it.
I would accept errors for more expansive play, work on skill execution at speed, encourage running in two's and three's with Roger Tuivasa-Sheck shadowing our big men up the middle looking for the offload. As a team you would want to focus on our individual strength's and not our weaknesses, our strength has always been second phase, our weakness is defence , so we would need to tire the opposition out with extended plays with offloads and spread of the ball.
I would re-sign Thompson as he has been a quality player over the years, mix up the backline a little as we have too many similar players in it. As good as he has been I would move Ayshford in to a bench second row/backline cover role, move Fusitua to centre and put CNK on the wing.
Lillyman would be getting his minutes gradually decreased whilst gradually increasing Vete, Gavets (when back from injury) and Lisone as they are the future of our forward pack and start giving Mannering rests here and there because he looks tired.
I'd also like to see us play more expansive footy, in saying that I do like that there's been an emphasis on ball control. Nothing pissed me off more than when we'd get into the grind and an outside back would drop a ball cold coming out of their 20m line.
Hopefully this is just the first stage of the (sorry for saying it) process. Hopefully the team have learnt how to respect the football so lapses like the ones we used to have don't happen anymore.
I'd also keep Thompson (maybe on less money than he's on now). He had a rough start to the season but has been fairly solid of late, I still think he has a lot to offer.
In hindsight it was probably always gonna be a 2-3 year effort to turn the club around given all the problems we've had. Hopefully we can stat seeing some results soon.
