I'll share my Faulk thoughts here like I did on the main board:
1:1, I think the Penguins say no. JJ is, at the very least, somewhat manageable at 3.25mil for the next 3. There is more of a possibility of swapping him in a crap for crap as well. Once you commit to Faulk for $6.5m for 7 years, that's much more difficult to manage and carries a lot more risk given Faulk's performance.
Sorry, I think the Penguins need an extra incentive. Maybe the 1st or Barbrashev or a quality prospect. Something to counter the risk. Ideally, a young center.
Keep in mind, the Pens taking Faulk allows STL to resign Pietrangelo. That's quite the favor. Certainly more gratuitous than StL taking JJ...
If JR was shrewd, he'd float this idea of the swap and then let it leak to other Central division GMs and other Pietro suitors. Then see if there isn't another team willing to snag JJ to keep this from happening...
