Frederic's toughness has since been tested in other ways. He was ranked 47th in the NHL Central Scouting's final ranking of North American skaters, but the Bruins selected him No. 29 in the draft. Bruins director of amateur scouting Keith Gretzky didn't do Frederic any favors after the draft, when he described the 18-year-old as someone who "is not going to be a top-two line guy."
Frederic didn't let anyone's words get him down any more than his broken hand did.
"I'm just kind of excited to be on the team," he said. "It doesn't really matter where you get picked. It's just what you do from there.
"I guess I've got a little pressure [as a first-round pick], but I think I like that. So it makes me push myself harder. So it's good."
Despite his short time to prepare for his first development camp after recovering from his injury, Frederic held his own. The Bruins think some of his skill was overshadowed by his smarts and savvy, but he showed playmaking ability and a strong wrist shot in addition to his intangible attributes battling against the Bruins' other prospects.
"What we saw and what he demonstrated [in his draft year] with the U.S. National Team Development Program and growing up amongst a real top group of kids out of St. Louis, he's a tremendous athlete," Bruins executive director of player personnel John Ferguson said. "He is big and strong [6-foot-2, 203 pounds] in the middle. That size and strength in the middle projects well. We certainly think, we're not going to put a ceiling on anyone at this age, but he does demonstrate the ability to be a real solid two-way center with size.
"So aside from that, we're seeing what we expected to see, and frankly we're seeing some of the hands that he demonstrated [with the NTDP]."
Frederic's offensive role might expand this fall as a freshman at Wisconsin, where he'll play for former NHL star Tony Granato. Frederic is used to being tutored by NHL alumni; he spent much of his youth in the St. Louis area being coached by Jeff Brown, who played 13 seasons in the NHL and sometimes Keith Tkachuk, a member of the United States Hockey Hall of Fame.
Frederic believes he can be more productive offensively, and considering what he did with one healthy hand, he might have more to give with two.
"For sure, I think I do," he said. "And when I'm put in a position for the offensive side, maybe I can do it and deliver," he said. "I think that's one of the reasons they picked me as well."
