He got them fit, he got them ready and he made them proud to play for Rangers. After that, it was all down to them.
Struth carefully selected certain members of the team to influence and direct play on the field. He had an eye for on-field "gaffers".
The men he chose to undertake the captain's role almost reads like the Ibrox Hall of Fame.
They included Muirhead, Cairns, Meiklejohn, McPhail, Gillick, Woodburn, Shaw and Young.
There were no tactical or formation changes. Struth was not a man of tactics.
There are also countless incidents of players declaring themselves unfit only for Struth to persuade them otherwise.
He would say: "What's this I hear about an injury, m'boy? When you go out there with a blue jersey on your back you're not going to bother about a twinge."
The message was delivered in such a convincing way that players were won over and aches and pains would no longer seem so bad.
It may sound as though Struth was reckless but his intervention generally followed a word from trainers about the nature and extent of the injury.
Struth always tried to ensure he had a good bond with the players. In the 1920s it was greater than at any other period.
He loved to play the piano which was located in the Blue Room and used it was a way of relaxing.
The Rangers players were an intimidating bunch but they enjoyed music sessions with Struth after training. Often the rugged group would waltz with each other to tunes played on a gramophone under the command of their manager.
