The Big issue is captaincy. Best is a cool man and there isn't a natural progression. Any backrower can't be certain of spot, Sexton I think struggles when that added pressure is on him. He is a natural leader anyway but get annoyed easy when getting in debates with ref, Murray not a captain type and no other real candidate.
Henderson has now been the Ulster captain a few times. While I wouldn't have thought him captain material, and still have large reservations, he might grow into it.
D4heads, how good is James Ryan? Could he be a first teamer in two years time? Seemed to do a decent job captaining the U20s.
Managing the referee is no different, the issue is being good enough to lead by example and always be on the pitch. Hence, how good is he and how good could he become?
