Try not to get too upset/crucify me for this proposal, I'm curious as to how you would feel about this:
PITs gains a cheaper version of Jordan Staal with less offensive upside in Hanzal. Staal is 4mil per year and for a team with huge centre depth that forces him to be a 3rd liner, that's a lot of money. Hanzal could fill that roll nicer and cheaper. Mueller (while the 'yotes have patience with him) could solve the winger problem on a team like PITs, playing with Crosby or Malkin could give him the confidence he needs to break out.
PHX gains a defensively responsible centre with good offensive upside that has been underused in PIT. He could easily slot into any line in the top 9 and play effectively. With Robert Lang being 39, his retirement must be imminent.
I still think PITs would have to add something else to this deal though to make it perfectly even.
Let me know what you think.
Throw in Orpik and a 2nd. That would make the deal more attractive....and fair.
