MTL decline obviously
If you can’t understand why a rebuilding team wouldn’t trade a 5th OA pick for one year of Marner, you are doomed

I'll be harsh (but don't get mad I'm not throwing that for you but at the player) : HABS do not need such a loser. Thank you

Montreal definitely declines.

Hard to say if Calgary would take Jarnkrok for free either, he wasn't at all good in Calgary before but maybe Huska can get more out of him than Sutter did. If so Jarnkrok could be a useful bottom 6 for a year or two. On the other hand he'd probably be blocking some prospects.

Why would the habs decline? They get the leafs 1st rounder and then they flip Marner at the TDL for another 1st rounder and 2 prospects. Marner double retention is only around 2.75M. So in the end they would give up Savard + 24 first rounder in exchange they get Tor 24-first rounder, 25-first rounder and 2 prospects.

1) The first trade has 0 retention on Marner meaning Habs are taking full contract
2) If this trade happens Habs will have 0 retention slots avalible to trade Marner at 50%
3) Trading a 5th overal pick for a maybe flip for a 20th pick and a prospect is a bad look and Habs could end up in a similar situation to the NYI with Vanek when they did that move or Arizona when they tried it with Hall, it would be bad asset managment

Sadly if leafs trade Marner they will have to bank more on quantity than quality coming back.

The 5th overall pick is worth more than anything they would get back for a Marner rental. This is all aside from the fact that Marner wouldn't waive to go to a rebuilding team anyway.
