Ah it’s easy to say that after all the English sides have lost. If results were different, or after another weekend, people would be saying something else.
Top one or two in England or France - you could argue the exact same about the Pro14. Only Leinster and Munster seem to be giving it a proper lash, with Glasgow and Scarlets (top of their respective conferences) doing poorly.
The Irish provinces rotate their squad, which is needed to bring teams on. If they played in the Aviva Prem, they would definitely still do the same against the likes of Quins, L. Irish, Worcester, Saints, Newcastle etc.
Leinster played Treviso before this round of Champions Cup games, rested players. They played Munster the weekend before Round 1, and put out a full strength team.
