Haven't the players Tayto.
You have to consider we've lost world class players in BOD, POC, Bowe and we've replaced them with Ringrose, Donncha Ryan and Simon Zebo. Ireland can beat anyone in the Aviva with a limited game plan delivered accurately with passion.
But we won't beat England in Twickers next year, France are incrementally improving too. It's a slow burner but they are definitely getting their since they've got Laporte in charge of French Rugby. He's got rid of the likes of Spedding and replaced him with proper playes like Dulin. He needs to turf the two wingers out next and they'll have a proper backline.
