Danny Schmidt’s most productive league campaign came in 2023-24 with Mainz 05 II, where he scored 13 goals in 31 appearances. For a developing player, that is the kind of return that at least gives a career a bit of shape beyond the usual vague talk of promise.
The available record is narrow, but the outline is simple enough: Schmidt built his strongest season at Mainz 05 II, with regular football and a decent scoring return. Beyond that, there is little need to dress it up.
