One of the difficult things to square up with rentals is that there seems to be a cap on what gets traded for them. I don't think Lindholm is going to fetch THAT much more than Chiarot (1st + mid pick + prospect) - I assume the prospect will be better, and the second pick is better as well, but I don't think the prospect is going to be a team's top prospect (whether that is Knies or another team's top prospect).
Teams know rentals are rentals. The value you get out of them is one playoff run. Historically that has capped what teams can maximize and is why guys all go for similar bunches of assets despite there clearly being a difference between the players, because even if you're trading for a top pairing guy - yes, he's worth more to you than Ben Chiarot - but he's not worth mortgaging the future considering the variance in the sport.
If Lindholm is dealt with an extension - obviously that changes things dramatically.
