Whether the training came because the Struths were by then staying within a couple of hundred yards of Tynecastle or they moved there because of the work is unclear but he clearly made enough of an impression to attract attention from Glasgow, specifically in 1908 from Clyde, where from the following year until 1912 he worked under the managership of the youngest of the Maley brothers, Alex. 

The family then moved itself to within half a mile of the Shawfield stadium, remaining there until, with Maley already gone in 1912, Rangers in 1914 appointed him as Assistant Manager to William Wilton and the Struths moving to Copland St. across the road from Ibrox. And there he would remain in place and position until the somewhat bizarre drowning of manager William Wilton in 1920, at which point he would simply step up, to stay in place for thirty-four years until retirement. And it is in that period that he and his club would win eighteen league championships, ten Cups and many other trophies, starting from his first full season and playing a style of football that was based on the standard Scottish game but with a Rangers twist. It was the rotation in attack and defense around first and ending with Meiklejohn, the Scottish Pivot and then, from the mid-1930s with Simpson, around the centre-back. All of which begs the questions, first, was the Rangers' system originally a product of the successes of the Wilton era or of Struth, the answer to which is unclear, and, second, how was it perpetuated, where the method seems to have been with Struth making sure of maximum fitness through the club's flow of senior professionals.
