A top prospect and 1st for Greene?
Also is it worth it to have Murray on the 3rd pairing?

Are you saying it's an overpayment or underpayment?
Right I should move Tyutin down.

Greene is very good and proven. Prospects aren't guaranteed(unless you are McDavid or Eichel, etc.).... and a 1st is unknown, could also be a lottery protected 1st, lol.

Columbus doesn't want this, sorry

Why not? They improved their forward group with Saad, and a full year with a healthy Bob is an improvement, the only area they could upgrade is defence. This move, along with a little bit of luck with injuries, may just push them over the hump into the playoffs.

I feel there giving up way too much for a defence man at 5 mil that's not worth it

The only way to do this deal is a nice Jersey girl or his current wife Brittany convincing Clarkson to move back to Jersey and Shero convincing Kekelainen to retain some money.
As I am unsure about how stable the marriage is, I am unsure which is more unlikely
Clarkson has a no trade clause, he's likely not be interested in joining a rebuilding Devils team, also I don't see the rebuilding Devils to take on such a contract at this time.
