Dallas coach Jim Montgomery credited Texas coach Derek Laxdal and his staff for Hintz's progress.
"Every time Roope went down [to Texas], he came back a better player," Montgomery said. "The last time he came up, he took his game to another level. You didn't see it in the scoring right away, but he was initiating plays, driving the play for us. We thought it was a matter of time before he broke through, and he did."
Hintz (6-foot-3, 215 pounds) is a strong skater who could shoot and pass like an NHL player even in the AHL. Laxdal said the forward has addressed what was missing in his game when he joined Texas last season.
"Now you're starting to see him engage in battles, win battles, and that was the part of his game that was lacking," Laxdal said. "And it wasn't because didn't want to do it, it was just being comfortable with it. He got comfortable with it at the AHL level, then he got back up to Dallas [on Jan. 29] and got more comfortable with it at the NHL level."
Hintz, who began the season with Dallas and was called up from the AHL four times, had five points (two goals, three assists) in his first 25 NHL games this season. After the Jan. 29 call-up, he had 17 points (seven goals, 10 assists) in his final 33 games of the regular season.
"It was like the Dallas Stars picked up a great trade piece at the [NHL Trade] Deadline, because he stepped right in," Laxdal said. "If you look at the upside of him, they're looking for the second-line center, and he sure stepped in and is doing the job."
