I'm very concerned about Sexton as well - the problem is that thanks to Joey's chocolate nature we don't really have many live options for 10. We have a number of options at 9.
Ross Byrne is fine, but that's all he is - fine. Carty is the only other option at the moment and he not someone I would be overly comfortable building a team around either. Burns is thoroughly uninspiring and Maddser (hair aside) hasn't had any form to speak of since leaving Leinster.
Realistically its going to be a couple of years before the likes of Harry Byrne and Healy put their hands up for selection.
It's a big f**king problem.
