Personally think JJ is only in the squad to bring him up to speed, with no intentions of him playing v Ireland - in the year he's had out England have got a new defence coach and a new attack coach, so much will be different so the more time he can have before the WC the better. He's been one of EJ's top performers since he took over the reigns in early 2016 and despite his year out is the joint top try-scorer for England under EJ (12, joint with Jonny May), he is an important cog for the WC.

Joe Marchant is one of the most consistent 13s in the prem, but test rugby is very different to premiership rugby, and we are pretty well stocked at 13 right now. He'll get his chance, but Manu, Slade, JJ, and Lozowski (Daly is another option and Te'o too if EJ plays Faz at 12 again), are all well above him in the pecking order. He's only 22, those four all have 3+ years on him, give him time and he'll be in and around there.
