Liverpool born centre half George Caddick began his senior football career on the books of hometown First Division club Everton spending 1924-25 on their books but never made the breakthrough to the first team before joining Second Division club Stockport County in the 1925 close season. He scored his only career goal for Stockport in a 1-1 draw in a defeat at Sheffield Wednesday that September and clearly impressed in a drawn match at Barnsley at the end of February 1926, such that he was signed by The Tykes within two weeks, whereafter he became their regular centre half.
It was said of him at the time: “The Barnsley club have produced many notable pivots, and their present centre half Caddick is a worthy successor to such stalwarts as Boyle and Barson, to name only two. Caddick shines chiefly in defence, and has subdued many notable centre-forwards both at Oakwell and on other enclosures.” However during his six full seasons Barnsley consistently struggled to maintain their Second Division status, and Caddick only missed 3 matches during their 1930-31 campaign as they finished a worrying 19th in the division. He lost his place in early December 1931 and played only 5 more matches as Barnsley were eventually relegated at the end of the 1931-32 season, and after 176 appearances for Barnsley he joined Southern League club Llanelli in the summer of 1932, his final known club before his eventual retirement.
