Daniel Sprong, F:A second-round pick (No. 46) in the 2015 NHL Draft, Sprong could finally become a fixture in the lineup with Sheary gone. The 21-year-old right wing could find a role within the top six forwards, possibly with Crosby and Guentzel on the top line, if he shows he can adapt to the NHL. Sprong scored two goals in 18 games with Pittsburgh in 2015-16 and three points (two goals, one assist) in eight games last season, but was sent to Wilkes-Barre/Scranton of the American Hockey League because his defense was lacking. ... Zach Aston-Reese, F: Unlike Sprong, Aston-Reese mostly stuck with the Penguins, who signed him to a two-year, entry-level contract on March 14, 2017. That was until the 23-year-old rookie sustained a concussion and broken jaw against the Capitals on May 1. After scoring six points (four goals, two assists) in 16 regular-season games last season, a healthy Aston-Reese could help the forward depth.
