Why isn’t Jonny Brodzinski a lineup mainstay?

Two seasons in a row Jonny Broadway has been passing the eye test and coming up with clutch goals. Why isn’t it good enough to stay in the lineup for a full season?

I don’t watch Hartford and I’ve only been following the sport since ~2022 so still plenty to learn. Please help me understand what makes Brodzinksi a great AHL player who’s used to plug the lineup and as opposed to a 3rd/4th line mainstay?
