The problem with a player like Madden who's been developing at just such an accelerated pace, that any sort of modest projection you make, will probably end up making you look like a fool in retrospect.
We're talking about a guy who was a controversial pick at the draft with many posters here outraged that Benning passed on Jake Wise. 2 years later. Wise has a whopping 5 assists to his career totals and is still hunting for his first NCAA goal, while Madden is one of the most dominant players in the US.
I'd be cautiously optimistic and say his ceiling is a high-end 2nd line winger, but it just feels like he's got that extra step that Horvat, Pettersson, and Boeser had, and is going to go much farther than anyone would have predicted. He's a legitimate blue-chip prospect that likely goes in the top 15 in a re-draft. He's been absolute find by Judd Brackett.
