My guess is if he has a strong year and he continues the consistency in which he finished last year with and started this year, he will be signed to an AHL deal for next year. They still have his rights until 2027 so no rush to sign him to an ELC yet. Go the RHP, Simoneau, Davidson route.
He was drafted as an overager, so unless he wants to continue his education, I don't think he'll do his 4 years of NCAA. I think they'll sign him to an AHL contract.
He might top out at the AHL level. But he has a skillset that not a lot of guys have. He has a nose for the net. He will go to those dirty areas and find a way to score the goal. And that's something Gallagher made a career out of. So you can't fully rule out Harris ever making it because not everyone is willing to get in there.
