I think this year the drop off after Celebrini, Lindstrom and Demidov to Eiserman, Catton, Connelly is large enough for there to be a reason to pick Demidov ahead of, likely Catton. Although we still have all of the most important club games left so we'll see.
Catton and Demidov are both rising their stocks. Lindstrom injured and Eiserman is what he is. Myself I'd argue that the order as it stands is:
Celebrini
Demidov
Catton
Lindstrom
Connelly
Eiserman
Then there's development to consider, guys going to NCAA:
Celebrini, while a college prospect looks like he will turn pro after just this season due to performance.
Eiserman is joining NCAA BU after decommitting earlier commitment to Minnesota. I admire his commitment.
And Connelly who is committed to NCAA Providence and to me it seems likely he will spend 2 years there.
The Russian factor:
Demidov is under contract for another year in KHL, which carries added risk regarding treatment from KHL club or simply Demidov's own will.
The simple junior route, "the sure thing":
Lindstrom and Catton who look like they will turn pro or return to juniors in WHL.
