There isn't really any space for Greenway on the Devils roster, not that I'd want him anyway. I think he's one of the most overrated guys in the league.
Stillman could be used as a base for a Fiala to New Jersey trade.

Sharks EASILY decline. Horrible

Can a Minnesota fan explain why Greenway has any value based on his price tag and production? I get points aren't everything, but like was said above, if he is just a depth guy, the Devils shouldn't be trading for that as we are already trying to move Zacha, Johnsson, and Tatar because depth is coming from youth movement (Holtz, Zetterlund, even Foote). If we only look at the offensive need (which ranks 3rd behind a goalie and a shutdown RHD), the Devils could use a fast forward for top 6.

Here’s my take…others will have different opinions.

Greenway, when engaged (and he has been most of this season) is a physical freak at 6/6 235 lbs. He’s an adequate skater (esp for his size), has decent hands and is a good passer with good vision. With his size, he is a force very few NHL defensemen can handle and he’s an absolute beast on the forecheck and the cycle!! However, I firmly believe thst if he was 6-2, 200 lbs, he would be a career AHL guy. But, he is 6-6, 235 lbs and is a very valuable piece to any good team. If he continues to stay focused and engaged, he will play another 10+ years in the NHL and be a very good 3rd liner who can move up the lineup when needed.

LMAO, that Sharks trade Easy decline
