I get you, but that's still an impressive jump from D-3 to an NHL organization, diploma in hand or not.
Ya know, I watch a ton of hockey on both sides of The Great Divide, and it can be very difficult to assess the talent re: D-1 v. D-3. I see a few individuals every year at the D-3 level who appear to have the wheels and hands to play anywhere in D-1, yet they never make it out of the low-minors when they turn pro.
Occasionally, there is a decent basis of comparison, such as when the U-18 team hammers a good D-3 squad, then goes on to be buried by a mediocre D-1 team a night or two later... (Still, it's hard to know how much stock to put into that, when you consider that even the best D-3 teams have a few bad players on their 3rd and 4th lines.)
I'm thinking that D-3 isn't scouted much at all... That's the only way I can make any sense of the situation.
