At first glance this is really bad for the leafs.
First off, why would we have any interest in upcoming UFA Nuge? To play 3c for a year and then walk? I also dont know why AA is there. Cap purposes? There is 0 interest there.
Muzzin is our 2nd best Dman and any Dman we are getting back is an immediate downgrade. Nurse could be there someday but for a team looking to win now it makes no sense. Also I take Sandin over Bear long term, quite easily.
A first and Broberg are nice pieces... for a rebuilding team. The fact that there is a 1 year rental, young players, prospects, and picks all in the same offer shows how terrible this really is.
And i didnt even mention the best piece in the trade by far, in Marner.
Value wise:
Sandin > Bear
AA >= Mikheyev (Same age, Mikheyev had a 0.59ppg, AA had .47ppg this season but is more proven. Both are RFA's, value is about a wash)
Muzzin =? Nurse (Muzzin is a bit better but also 6 years older. Value isnt far off)
So would you trade Mitch Marner for pending UFA Nuge, Broberg and a mid first?
