I didn't say he's guaranteed to be an NHL player, but anyone who can have a lasting career in the NHL taken beyond the third round would be considered a hidden gem in my book.
Alec Martinez was a hidden gem, as was Dwight King.
There's this thing called a "late bloomer" which is what Brodzinski was. Maybe you should do some research and not assume things. I guess those taken in the first round have no flaws right and anyone taken beyond that has a bunch of flaws? Some sound logic right there. You should be hired to scout talent.
