Eichel was one of 11 players invited to camp who represented the U.S. at the 2015 WJC in Montreal and Toronto. Eichel had one goal and four points in five games as captain of the team, which lost to Russia in the quarterfinals. He signed an entry-level contract with the Sabres on July 1."I think in the end we're looking at the best interest of the player and I'm sure Jack has a lot going on with Buffalo in terms of development camp and preparing for the NHL season," U.S. national junior team general manager Jim Johannson told NHL.com. "We're also realistically looking ahead, for our team. The odds are we probably wouldn't have him even if he were invited."
