Werenski isn't going to wait 4 years to be in the NHL. You can blow this fact off for the "sky is falling" thinking all you want, but those are the facts. Pat Brisson is the "family advisor" to many college kids.
Pretty much this.
Whether he plays in the OHL or the NCAA for the next two years, it doesn't really matter. Werenski, unlike Reilly, isn't a long-term prospect that four years from now is going to spurn the CBJ and go sign with another team (in this instance, for argument's sake, the Detroit Red Wings).
He's a very high profile, top-10 NHL draft pick. When is the last time any of you saw a top-10 NHL draft pick refuse to sign with the team that selected him, and how did it work out?
Perhaps the most notable is Eric Lindros. Not that I'm comparing Werenski to Lindros, but, in that instance, the Nordiques knew for a long stretch of time that Lindros wasn't going to sign with them, and were able to parlay him into multiple Stanley Cup champions, acquiring several pieces that became key parts of those Cup winning teams in Colorado.
Frankly, there's a big difference from a fourth round pick that develops nicely and could become a middle pairing defenseman, and a top-ten pick that should be in the NHL in two or three years. The Jackets will know if Werenski wants to sign with them or not well before he's allowed to walk away from the franchise. You don't take chances like they did with Reilly on a top-ten pick.
Give Jarmo and JD more credit than that
