Has there even been any indication from Farrell on the style of rugby he's going to play?
He hasn't been a head coach for a long time and if it goes bad he won't get the chance again.
Think of it this way. You're Andy Farrell, part of Joe Schmidts boring style but you're seen as very successful.
Would you stick with what you know? Or risk more expansive and potentially embarrass yourself? Andy Farrell personally would jump at the chance to replicate the last 6 years even though world cups are disappointing.
I think it'll be the same old boring rugby and then against Italy and the likes we'll throw it around and people will claim he's doing great and playing more expansive despite us doing that under Joe anyways.
