Sam Underhill (England): The England flanker has an all-round game well suited to Sevens. Turnovers at breakdown, high work rate and great handling skills all add up to a big impact for Team GB.
Jonny Gray (Scotland): Every sevens team needs a kick-off and lineout specialist. No one fits that bill better than Scotland’s sensational Gray. His aerial ability and all-round athleticism is up there with the best. Tackles, turnovers, off-loads and bags of enthusiasm – Gray would bring a medal-winning game to a Team GB Sevens team.
