I think the key to a successful 2C is the ability to think the game. Krejci is having a great playoff series. Pretty sure Trocheck is considered a slightly better skater. However, Krejci seems to think the game better than most 2Cs. In that way he is similar to Couture, and Point two of the other top 2Cs (though Point has become a great skater and is the 1C for many purposes in Tampa). My point being that I think hockey IQ should be targeted by the Canes.
I am not a scout, but I have subscribed to both McKeens and HockeyProspect's Black Book. The latter had three elite ratings for hockey IQ: Lafreniere, Perfetti, and Brisson. I would target either Zary or Brisson in the first.
Game reports from both scouting services mentioned excellent hockey sense when discussing Theodor Niederbach. The organization should target him with one of the second-round picks.
The organization already has good skaters in both the NHL (Foegele, Slavin, Skjei, Svech, Aho) and prospect ranks (Keane—who if I remember correctly clocked a time close to the McDavid range in the AHL skills competition, Rees, Fensore). With all those players flying around the ice it is really beneficial to have players thinking the game quickly.
