Laine and Puljujarvi were linemates and helped Finland win the gold medal at the 2016 IIHF World Junior Championship in January. Matthews was part of the U.S. team that won the WJC bronze medal.
Matthews (6-foot-1, 210 pounds) tied for the tournament lead with seven goals in seven games, tied for the U.S. lead with 11 points and was named to the tournament's All-Star Team. His goal total was one short of Jeremy Roenick's U.S. record set at the 1989 WJC.
Laine (6-4, 206) tied Matthews for the WJC lead with seven goals. Puljujarvi (6-3, 203) led the WJC with 17 points and was named the best forward and most valuable player of the tournament. His point total was the second-highest by an under-18 player at a WJC. Jaromir Jagr of Czechoslovakia had 18 points at the 1990 tournament.
After the three drawings, the 11 remaining teams will be assigned draft spots No. 4 through No. 14 in inverse order of regular-season points. Castron said the 2016 draft class is deeper than maybe some might want you to believe.
"If you take away Connor McDavid, this year's draft is as good or maybe even better than last year when you begin ranking the top 15 players," he said. "There are some dynamic players in this class, even where we're sitting at No. 11 in the order. I'm pretty excited about who we might get."
Among forwards, the top players include Pierre-Luc Dubois of Cape Breton of the Quebec Major Junior Hockey League, Matthew Tkachuk of London of the Ontario Hockey League, Alexander Nylander of Mississauga (OHL), Julien Gauthier of Val-d'Or (QMJHL), and Clayton Keller of USA Hockey's National Team Development Program under-18 team.
There also are quite a few defensemen who could be selected in the top half of the first round.
"I do think it's tilted toward the forward position, but defensemen Mikhail Sergachev [Windsor, OHL], Jakob Chychrun [Sarnia, OHL], Olli Juolevi [London, OHL] and Jake Bean [Brandon, Western Hockey League] are probably the defensemen who everyone has in some sort of preferred order," Castron said. "Any one of these guys could go at any point and once the first one it taken, there could be a run."
