well I didn't mention him cause I thought he was good. it was a salary dump from their side.
Of course, still he's a viable vet option if you move Smith out or Staal moves on in some capacity. But as you stated, you're paying for it on the cap. I'll echo Edge and say Vegas isn't a good dance partner for the Rangers.
To make a move, imo you either have to fleece a team, get something for a bailout, fill your own holes, accumulate value, or make a change of scenery deal- salary cap not withstanding, those would be the reasons why I would want to make a trade. Vegas doesn't offer anything in their current situation that helps the Rangers get a premium.
I think you either deal with cash strapped teams, teams that want to make a trade up at the draft, or teams that will help you fill needs. There will be more activity then ever with a known quantity for a cap for the next couple of years.
The teams with the foresight- IE cap and salary management- will have a competitive advantage in a far more fixed playing field.
So I would say situations like ARI (who will have close to 30 suitors), CGY (relationships and immediate needs), DET (can't embarrass themselves as much) and others are better candidates to help the Rangers out. STL is another, they need to take some measures depending on their cap situation. You're going to be able to get a good winner from that team, but they can get around it but using the Brooks Orpik loophole.
