It's way too early to be projecting him as a #2 C in the NHL. He would need to produce significant numbers in the AHL first before I would feel confident projecting that.
It sure looks like he has the tools to be a quality #3 C though, he's been shutting down 1st round caliber talent during this run:

One of the best things about Michael McCarron's turnaround is that he's pretty much annihilating his match ups (the opposing first line).

Travis Konecny, Jared McCann, Robby Fabbri among the centres he's been matched up against & has thrived. Played well against McDavid, too.

Against Travis Konecny, Jared McCann, and Robby Fabbri (3GP), Michael McCarron has a collective 10P. Those three have a combined 1P.
Some McCarron quotes:

McCarron looks like the player the Knights thought they would get last year and that the Montreal Canadiens believed they were getting when they drafted him in the first round. He’s more confident, quicker and tough to handle.
“Speed and conditioning, everyone would say that,” McCarron said when asked about his improvement. “I look faster. I could play a full 60 minutes this year rather than last year when I would play 10 minutes and I was gassed.
“I knew what I had to do in the off season and I did it and came back in good shape. I lost a little bit of baby fat and came back a little bit stronger.”
Knights’ assistant coach Dylan Hunter said it took a while for McCarron to figure out the league and what he had to do in order to be successful.
“You have to work on everything day-in and day out,” Hunter said. “I think this summer he took it personal and got in great shape. We had a day off and he came in and worked out. Kudos to who he had as trainers in Montreal but kudos to him the most.”
