Tj Brodie has been such an amazing dman for the Leafs. We shouldn't trade him.

If that were Muzzin then sure, but not Brodie.

Current roster:
11 forwards = $43.3 million
4 defenders = $17.5 million (Doughty, Roy, Walker, Spence)
2 goalies = $10.8 million
dead cap = $2 million
Subtotal = $73.6 million
Grundstrom = $1 million or more
Vilardi = $1 million or less
Turcotte, or other promotion from Ontario = < $1 million
Anderson = $2.5 million or more
Durzi = $1.5 million
Total = $80.6 million or more
Amount remaining for one LD = less than $1.9 million

So Kerfoot is simply out of our reach even if we had an open slot on the roster.

Pit says no... the trade makes zero sense for them. Pittsburgh has Matheson, Dumo, and Pettersson all on the left side signed to big money. As well, even if Brodie were to play off hand, he's not taking Letang or Marino's place so...

Then you factor in that Pit is already a super cap strapped team, if anything they'll look to move out one of those LHD not bring another one in...
