I really liked Stuart Munro, a no nonsense fullback who took no prisoners.
Grew up with Wullie Mathieson although enjoyed John Greig playing there especially that match against them when he snapped i think Bobby Lennox? then ran the length of Ibrox to tap into an empty net.
Big Sasa playing out of position did a great job as did Numan but gonna go for Davie Robertson, what an engine he had in him and i believe he would fit in seamlessly to the modern game.
