#3. Greig Laidlaw (Scotland)
Two Scotland legends. Uncle Roy was capped 47 times at scrum-half for the dark blues between 1980–1988, and British Lions in New Zealand in 1983. Nephew Greig, who is also a scrum-half, was the captain of the Scottish national team from 2013 until 2017 and has currently won 63 caps, scoring 623 points. He also, like his uncle, toured New Zealand with the British & Irish Lions in 2017.
