Here's something else to consider.
Bobby Mac's recent scout poll had 9 of the 10 scouts with Schaefer at #1. Almost all scouting services have him at #1. A lot of fans are just now coming to the draft party and are not seeing a lot of hype about some generational prospect and the fan consensus is "it's very cloudy at the top". The truth is Schaefer, among scouting types, is clearly the #1 guy. Not overwhelmingly the #1 guy, but clearly.
Now, understand they are coming to this conclusion with a guy who played 22 games and 4 periods of the WJC (during which pre-injury he looked fabulous). If he doesn't have that broken clavicle - I fully believe this is already known as the "Schaefer draft" and this thread is on page 60, not page 18.
I get it. He's a defenseman. They historically don't get taken at #1 and even the top guys tend to take longer to "get results" from. Add in the injury. Add in that it is much easier for fans to sort scoring totals and go "goo-goo eyed" over mouthwatering forward counting stats. Offensive forwards are sexy. And yes - given the smaller sample size - there is inherently risk here, a bit of a leap of faith.
Now consider the character, determination and bounce back ability of the kid you are putting that faith in. Now consider that despite everything I just listed; almost all scouting services and scout polls STILL have him at #1.
I think this kid is special.
