I wouldn't say Moriarty was on fire but that's probably just another thing we disagree on. Moriarty is a solid international class player but he's no world class player in my book. Wainwright was decent in the World Cup and has a much higher ceiling than Moriarty but again, not in the same league in my book.
In my opinion if Navidi and Faletau were fit they would've started the game for sure.
I'm a big fan of Ellis Jenkins to but there's no point discussing him as he's only just come back from injury and was injured at the time of the World Cup.
