Craig's football career began with Rutherglen Glencairn. The family was by then been back on the Clyde for the best part of two decades, living in Hutchestown, he having begun his working-like in a Gorbals biscuit-factory. He was signed by Ibrox in 1905, aged nineteen and over the next seven seasons made over one hundred appearances. That was before a season's loan at Morton, which became a transfer in 1912 for two more. By then he was in his late-twenties and, whilst he had two more wartime years back with the Gers to 1916 and a spell with Johnstone outwith the League his career was part-time with him otherwise employed as a Wine and Spirits Salesman. It was a role he was to stay in until his death.

Meantime he has also married, to Janet Black in Blythswood in 1914, he by then living in Mount Florida within sight of Hampden. And it was there they would settle and have two children, two boys, Charles born in 1915 and James in 1918. However, Janet's health was clearly not good and, with them now leaving in Holmlea Road in Cathcart, in 1928 she would be admitted to old Victoria Infirmary opposite today's and there die at the tender age of just forty-one. And, in fact it would be Holmlea Rd. where the boys would be raised, Alex never remarrying, and from where Alex himself would do again to the old Victoria Infirmary to die in 1951 at only sixty-four. Where he is buried is not yet known.
