Evgeni Malkin and Kris Letang were named to the 2016 NHL All-Star team today. They will be the two representatives for the Pittsburgh Penguins this season. The NHL has adopted a new 3-on-3 format, broken up by division, so the roster is only 11 total players per division. Each of the 8 teams in the Metropolitan Division needs to be represented, so there wasn't much room for extra players. If anything, it's surprising to have 2 all-stars.
But it's certainly no surprise that Malkin is at the top of the list for Pittsburgh.
