So, Auckland got dicked by the VAR applying "not enough contact" for the cynical shirt pull in the first leg in Adelaide, and got dicked again by VAR ignoring that same rule in Auckland.
Swing those round the correct way and Adelaide is back in 6th and Auckland is 12 points clear - that's fairly significant implications.
