I'm sure the Sens are wild for Cutter Gauthier, but I don't expect him to be available at 7. Pierre Dorion and Trent Mann would sprint up to the podium to make that pick.
I can't see them taking Kemell, really. Ottawa have been very transparent about their unwillingness to take risks on flashy skill, particularly on smaller players. For example, since 2017 the Senators have made 34 draft picks and only 1 of those players stands shorter than 6'0" - that's a very strong size bias. I think Kemell's 5'9.5" measurement really hurts him in this case. Small wingers that don't project as special talents commonly slip down the board on draft night.
Likely the first 6 picks will be Wright, Cooley, Slafkovsky, Nemec, Jiricek and Gauthier in some order. So, much like last year, Ottawa's pick is where things could get a bit weird. At that point, most of the consensus 'best players' [Kemell, Savoie, Lekkerimaki] are guys that the Sens aren't likely to have as the 7th name on their board.
I think Kasper is a fit, and I don't even really view it as much of a reach. He's an appealing player - easily projectable into the NHL.
