That's what i said right at the start, because you suggest it, does not make it true.The bulldogs beat richmond in 2017 at etihad.
So i consider that a fair assumption that interstate the tigers would lose again.
As for the hawks game - once again that would be an interstate game for richmond - and seeing as richmond havnt beaten a top 4 side interstate in the last three seasons id suggest an interstate win against hawthorn in 2018 would be improbable.
Hawthorn just don't beat Richmond, just like Collingwood don't beat Hawthorn.
North last beat Richmond i think in 2016, when Richmond struggled, but oh look, you have them winning also.
