I think his options are stay out or go abroad. He's obviously comfortable in Leinster and might see Conan's spot up for grabs in the next 12-18 months.
Otherwise I don't see him playing at a standard high enough to get him into Ireland squads elsewhere. Coombes, Prendergast and Timoney are all playing out of their skin to fight for the honour of holding a rucking shield for Josh Van der Flier. Connors also offers a very specific skill set that would really suit the international game.
In any case staying in Ireland means fierce competition for minutes.
Going abroad and making a wedge seems like the logical option but maybe he just doesn't like being away from home. Not unusual really.
