In the 2018 pre-season the Toronto Maple Leafs kept the newly drafted Semyon Der-Arguchintsev in camp longer than anyone expected, and he made his Scotiabank Arena debut in a pre-season game before being sent back to the Peterborough Petes of the Ontario Hockey League. His long time in camp and how easy it was to give him a nickname - SDA is much more memorable and easier to type - that he became one of the Leafs most talked about prospects of that draft, probably more than first round pick Rasmus Sandin.
An easily remembered prospect is always under a bit more of a microscope, and one that plays in the OHL near(ish) to Toronto gets even more attention.
