And with the Top 4 on D being tasked with huge minutes right now, it couldn't have come at a better time.
"I think when I'm skating, when I'm moving the puck quicker, that's when I'm at the top of my game," said Weegar, who played north of 25 minutes for the second straight night. "You can say what you want about new systems and all that, but I think we're over that now. We're 10 games in. Five games in it wasn't an excuse. We have to know the system by now.
"I think I was skating well (last night). I thought the whole team was skating well. Just had a couple bad turnovers and that was really it.
Weegar has been a stellar addition to the Flames blueline and with injuries to Chris Tanev and Michael Stone now adding to the brigade's workload, the 28-year-old is truly finding his stride.
"It'll come," Weegar explains. "Everyone wants us to produce more, but I think we all as a team just have to be committed to what our identity is and checking hard and playing fast. Just playing the smart way, competing hard. The effort's there and the production will come, I'm sure.
"It's a long season. But with Jonny (Huberdeau) and I, just stay positive with each other.
"That's what your teammates are for. It doesn't even matter if it's Jonny, it could be anybody on the team. There's a great leadership group in there and some great guys on the team. You could say that it's a little bit of a slump or times are a little tough right now, but that's when everyone gets a little closer and that's when you need your teammates the most."
Last night, it became clear that the Ottawa native has officially taken that step.
Prior to Saturday, when Stone went down with an undisclosed ailment, Weegar was third on the team with an average ice time of 20:49 per game.
It may not sound like much, taxing his body with only a four or five-minute increase per night (or eight, in the case of Saturday), but Weegar has handled it well.
Last night, he was a game-changer - skating with confidence, transporting the puck and even getting involved offensively with an impressive five shots on goal (second only to Noah Hanifin).
"Part of being a good pro is taking care of your body," he said of the workload. "After the game, getting treatment if you need treatment, getting in the ice tub, whatever you need to do - you have everything you need in there.
"We have a great therapist group in there that can take care of your body, but it comes down to you and making sure you've the right things in your body and are mentally ready to play big minutes.
"For a lot of guys in this league, I think it's more the mental side than it is the physical side. It's a fast game out there and you're going to put your body on the line a lot of the time. But when you're fatigued, that's when your mental state kicks in and you've got to grind through that part."
Right now, there's no other choice.
Connor Mackey and rookie Nick DeSimone - who made his NHL debut last night at UBS Arena - have given the Flames good minutes on the backend.
But tonight, the veterans will again draw the heaviest assignments, and another toll of 25 to 30 minutes per is expected as the Flames visit the Devils.
They'll need everyone on board to "grind through" it and finally crack this 0-3-1 slide.
"It's just about staying positive," said Weegar, a who was drafted here at the Prudential Center back in 2013. "Obviously, there are little things (to improve on). Turnovers, maybe some puck management things that we maybe need to start learning from our mistakes. Now.
"We're 10 games in. We need to be better at that stuff, but we have a lot of things to build off (from last night).
"They're super small mistakes, but in the NHL, it's the little things that will hurt you. It's just those little turnovers, those little plays and maybe getting pucks deep, finding a man, boxing a guy out, having a good stick, tight gaps. It all builds up.
"The good thing about this road trip is that we get to bounce back right away."
