McKenna (6-foot-2, 190 pounds), who played two games with Dallas this season, offers a calm, positive presence amid that playoff pressure. He is 11-4 with a 1.97 goals-against average and .940 save percentage in the postseason.
Joining McKenna to help shepherd the young players are forwards Curtis McKenzie, 27, and Travis Morin, 34. Each won the Calder Cup with Texas in 2014.
McKenzie (6-2, 205) is tied for third with Rockford defenseman Adam Clendening in playoff scoring (14 points; six goals, eight assists in 15 games). Morin (6-1, 190) has eight points (four goals, four assists). Their strong play has eased the burden for a talented cast of prospects.
Rookie forward Roope Hintz (6-3, 205) has continued a strong playoff performance that should make him a contender for a full-time job in Dallas next season. Chosen in the second round (No. 49) of the 2015 NHL Draft, Hintz, 21, scored the game-winner in Game 6 against Rockford and is second in rookie playoff scoring with 11 points (four goals, seven assists) behind Rockford forward Victor Ejdsell (12 points; seven goals, five assists).
Playing on an AHL contract, 24-year-old undrafted rookie forward Sheldon Dries' seven playoff goals are tied for the AHL lead after his 19-goal regular season. Any questions about his size (5-9, 180) are answered by his willingness to compete for loose pucks in difficult areas of the ice.
Forward Jason Dickinson (6-1, 185), selected with the No. 29 pick in the 2013 NHL Draft, split the season between Dallas and Texas. The 22-year-old has had to overcome injury problems early in his career, including hip surgery. However, he scored 18 goals in 42 AHL regular-season games and has eight points (two goals, six assists) in 15 playoff games.
