Almost no chance is going a bit far for Ross, there can't be a massive gap between him and Carty and it's not unlikely we take three 10s especially if we want to give Sexton a proper rest. It's also not unlikely that Sexton misses some part of the European/Pro14 knockout games given his injury record, if Byrne steps in and plays well then it's a big boost to his chances. And anyway with Carbery and Sexton as our no1/2 injuries are practically inevitable given their track records. Anyway the pre-RWC training camp has a big impact on World Cup squads which makes it much harder to call from a fan perspective. I don't think Adam Byrne has a massive chance but if I was picking the squad he'd be right up there. We'll see who lines up against Ulster but Byrne has probably established himself as first up after the Lowe/Larmour/Kearney trio in the Leinster back three which given how often we can't pick Lowe because of annoying rules and how often Larmour is pushed to 15 to cover for Kearney's never-ending injuries is a pretty great position to be in in terms of getting on the pitch in big games. He'd probably be behind guys like O'Loughlin (another guy who Schmidt/Farrell should give another look) and Tomane who can cover multiple positions on the bench but that's not the end of the world. Either way it's mad that Jack McGrath isn't in these squads given he was one of the top props in the world a few years ago but it's probably the best way to go in terms of numbers up front. Amazing how the chips fall sometimes.
