He’s committed to another year in college we won’t be able to add him until after the college season is over

He will be an addition after his NCAA season is done. May be a good addition for the playoffs!

As touched on above, he won't start his year with the leafs but maybe at the end? I'm not sure how it works in the playoffs though, I don't think he'd be elidgable unless he signs before the trade deadline, which he'd have to cut his colledge season short. You can bet he'll be on the team in 2023-24.
