Matthews is going to get more $.
Bunting isn't a 5.5 mil player.
Boyd isn't worth assets.
Crouse trade is an overpay.
If Samsonov ends up having value to be worth signing for 5 years, he doesn't settle for $3mil through his prime years.

Oh, and the Murray buyout also costs you $2mil the following year, no chance.

As a Coyotes fan:
Boyd is worth AN asset. A late 3rd or a 4th probably, but not what OP suggested.
Crouse trade is an overpay. Could probably return a 1st this year plus a B level prospect but doubt Coyotes move him.

W username and im a yotes fan too but i see boyd being worth a decent pick with a solid contract and if he keeps this scoring up. crouse probably isnt going to be traded but if a big enough package comes in then yeah id do it and for the leafs he seems like a good fit
