Okay, so I'll take the bait and offer some thoughts on your rankings:
First, the forwards. I don't think Tresca warrants being in the top tier. Yes, he's had injury issues, but he's not a top-six forward by any stretch. I would put him in the lower tier. We don't know anything about Will McDonough because he didn't play last year. So that's an incomplete.
The Defense. Healey does not deserve to be in the top tier. He is a giveaway machine in the D zone. He does have the offensive skill that would be better suited up front, and I would move him to one of the top two lines next season to add some punch. We haven't seen enough of David Hedjuk to form an opinion. Will likely get more ice time next season unless the freshmen are appreciably better.
Goalies. We know what Charrette can do, so that's a lock. They need to pick up another goalie because Zhang didn't play, and he is a wildcard. Not being able to use the transfer portal hurts Harvard. This is only going to get worse as the years go on. I don't know how they will be able to compete against non-Ivy foes inside or outside the ECAC.
