A different game plan solves everything = Magical thinking.
There are 18 teams full of professional athletes and staff who are all busting their arses trying to do a little better than everyone else. In this environment, a successful team is not going to need a better game plan to reach the top, they are going to need a slightly better everything to reach the top. This won't happen by recruiting a coach or a set of coaches that can nut out some super game plan that mysteriously can't be disrupted by the opposition. It comes from years of developing and improving everything. All this stuff has to occur in a flat out competitive environment, working at the limits of what people know, and what what players and coaches can do.
Even then, luck and timing play a big part. Most recruits fail to make 50 games, no matter who selected them. Despite best efforts of everyone involved, injuries remain unpreventable and random and this affects team performance. The draft and the salary cap, by design, produces cycles of success and failure.
What we want is a culture of management and development in all areas that persists despite changes in personnel. As far as I can tell the club - including RL - are fully committed to this.
The magical fix idea is crazy, but what is worse is it is the road to failure. Once everything else is working the game plan is the easy part. If it was just the game plan, everyone would have done it and 18 teams would win the premiership every year.
For every complex problem, there is a solution that is simple, neat, and wrong.
