He spent most of the campaign on a line with Tkachuk and Mikael Backlund, with the trio forming a dominant, symbiotic partnership that allowed all three to thrive, despite the heavy, defensive responsibility.
But Mangiapane, in particular, was a real driver on offence, with no other Flame besting his head-turning, 53% Corsi-For stat.
Now, with an increase in gravy minutes likely to come in his future, Mangiapane knows he that has plenty more to show.
"Even at the start of this past season, I was playing (fewer) minutes and starting out on a lower line, waiting for my opportunity," he said. "Then, things changed.
"I got the opportunity and started playing more minutes. Hopefully, I can start to play more on the powerplay, too, because I still think there's a lot of room for me to grow, and a lot more for me to show, offensively. I'm still trying to prove myself, but I know what I'm capable of, so I can't wait to get back on the ice so I can do that."
Mangiapane has now earned himself a nice raise, while the team locks in a young stud at a fair price to ensure they can properly fill out the roster and assemble a contender for the upcoming season.
A win-win.
