You could probably get Hall for less since money doesn't seem to be his main concern.

Ideally, that'd be nice so I could find a better 3C who can PK.

Disagree with this.

1, Consider who the agent is, Darren Ferris, same guy said client Mitch Marner would take discount for Toronto.
2. Hall wants to be on perennial playoff contender. But is someone that does want to move around a ton. He has historically has adjustment period with new teams.
3. I'd think 3-year deal would be shortest-term he'd consider (somewhere between Mark Stone and Jeff Skinner's salary)

For Hall, would ballpark his contracts

3-year $9-9.5 million
7-year, $8-8.7 million
