[Sportsnet] “Prospect of Interest: Why James Hagens enters draft ready to silence doubters” | The reason Hagens is dropping in the draft?

I was talking to someone in r/hockey about Hagens falling as low as 10th place in some mock drafts. I stated that I found it hard to believe that so many candidates could rise above Hagens because of their combine performance eclipsing his instead of his own stock falling. I learned, however, that there might be something else at play.

Apparently, there are some reports that Hagens wasn't giving the right answers in interviews. Seems that instead of looking back on his disappointing college year and explaining how he could improve, he came in with a chip on his shoulder and focused on his past performance.

I couldn't quite find a source that says exactly this, but the linked article does seem to hint at it:

At the NHL Scouting Combine in early June, there was a sense James Hagens believed he wasn’t getting enough credit for the year he put together with the Boston College Eagles. Hagens entered the season as the projected first-overall pick on many draft lists before slipping down most rankings in the back half of the year. Unsurprisingly, the talented Long Island kid thought he might be getting short shrift, as the hockey world began to talk more about the likes of Matthew Schaefer, Michael Misa and Caleb Desnoyers. 
…
Hagens is highly motivated heading into the draft. He was pretty open about the fact he feels like he deserved more respect for what he accomplished this season and that people are underestimating how good he is. 
…
As it happens, part of what makes the modest-sized Hagens special is the fact he’s played with a chip on his shoulder long before any perceived slights.

I wonder if this is really the case, and Hagens is dropping because he's perceived to have an "attitude problem" in addition to his "size problem". Just going off vibes, I can kind of see it. In that fluff hype video that the NHL made about what each prospect's greatest fears were, Hagens was the only one to give an out there answer: "Not winning the Stanley Cup".

If indeed so, that's kind of interesting. On one hand, the further Hagens drops, the better for those of us who would like to take him. On the other hand, attitude is always a bit of a risk. Does it mean he's hyper competitive, or does it mean he's stubborn and might have a hard time developing his game? How much should the Isles fight to take a chance on him, if given a good offer to trade into the top 10?

Of course, there have been prospects that have been rumored to have attitude problems (and size problems) before, have dropped in draft stock, and ended up being pretty good picks after being taken. You might even be familiar with one of them, his name being, of course, Matt Barzal.
