"I've learned in the hard way in the past, crossing that line," Rinaldo said. "No one ever wakes up and says, 'Hey, I'm going to try and get suspended tonight.'
"But I do think my role matters, and that I can provide a lift for my teammates with a big hit, a blocked shot - anything.
"My goal here is to show the coaching staff that I'm more than that one-dimensional guy they may have heard of."
So far, so good.
In fact, Bill Peters went out of his way during the first day of camp to mention Rinaldo as a player that stood out.
Then, when asked earlier this morning to summarize the Mississauga native's debut the other night, he, again, left a positive impression.
"He was good," Peters said. "I thought he and (Devante) Smith-Pelly got on the body. He led us in checks, I'm sure of it. ... They play to their identity, so it was good."
Rinaldo will play a similar, fourth-line role again tonight as the Flames host the San Jose Sharks in the second of eight pre-season tilts, with the vet lining up on the right side next to prospects Adam Ruzicka and Martin Pospisil - the latter, too, known for his own brand of pushy reconnaisance.
"On Monday, I thought I was physical, brought a lot of energy, made plays with the puck when the opportunity was there," Rinaldo said. "That's a big win for me, personally.
"Now, with that one under my belt, I want to slow down the game.
"I think when I get a good grasp of how much time I actually have to make plays, it'll become easier. … To be away for so long that and hop into that pre-season game, it felt like I wasn't missing a step. If anything, I was a step above some of the guys on the other team.
"I have to do it again tonight. You never know how many chances you're going to get, and this is a great one to show everyone:
"'I'm back.'"
