I don't remember many but to be fair I didn't watch a young Alfie.
One of the best indicators I have found for great players is that even when they have bad games they are still creating or trying to create. Karlsson, Alfredsson, Stone, Spezza all would make dynamic plays even if they were struggling because they were simply on higher intelligence and skill level than most players on the ice. It was second nature for them to make high end plays.
Brady doesn't struggle like that, he straight up vanishes so that the only time you notice him is when he makes a big hit, dumps the puck in to go on a change, or turns turns the puck over.
And its not even that its singular isolated dud games. Since Batherson went down, it's been many, sometimes consecutive games where nothing happens with the puck on his stick.
