Or ..... we've dumped an overly conservative coach who failed when it mattered (3 in 13) and who oversaw a very poor record at home for a more experienced coach who can build on the good bits of Rosenior's tenure whilst bringing a more positive attacking possession based style?
I agree in that it might work or might not. It was ever thus. Only TWT.
Why the dramatic take?
Good thinking that bring someone in to improve the attacking which was being worked on and sacrifice the defensive part swap it round makes sense.
