Over and above the infectious crash-bang he injects, Hathaway chipped in with 11 goals, 19 points and finished +18 to, as Peters mentioned, solidify a spot in what has become a deep, talented lineup.
"I think I've got a good regular-season to build off of," Hathaway reckons, the final countdown underway to his first-ever top-level post-season appearance.
"I've never been in a NHL playoff game, but I've certainly watched a few.
"What I want to do now is what I always want to do - help the team as much as possible.
"The atmosphere around here is amazing. We've got a city full of fans who are as pumped about this as we are. And that's something we have to manage.
"There are a lot of different excitement now and with a group that hasn't collectively played a lot of games in the playoffs, we have to grow together, be even keel, manage our emotions, both the highs and the lows."
Playoffs are traditionally the time in any season when the unsung are sung about; when 'that' type of player - meaning the in-your-face, give-no-quarter sort - are more noticeable on a broader canvas, discovered by a different audience.
The NHL history scrolls are chock full of 'em.
Can Hathaway be that sort of revelation this spring?
"He's going to have to be, given what he has to bring to our team," parries assistant coach Ryan Huska. "At this time of year, there's a greater acceptance of, a greater interest paid to, role players like Garnet.
"That's why maybe you see a name you're not expecting pop out of the woodwork.
"Hath kills penalties, does a really good job with that. And when you look at that line 5-on-5, he's the guy that creates the loose pucks by banging and crashing around.
"When he's at his best, he's dragging people into the game and getting opponents mad at him, often because he just plays so darned hard."
