This isn't the first time the Toronto Maple Leafs have failed to win a game where their top prospect makes their NHL debut.
The team infamously lost 5-4 in overtime in Auston Matthews' legendary debut almost a decade ago (crazy right).

Let's take a look at Cowan's performance on Monday afternoon and what this means going forward for the Leafs.

The former OHL MVP was thrust onto the Leafs top line for the game vs Detroit, and he did more than fine.
