VERY STRONG NO. both in terms of if I would do that deal as DL, and how bittersweet seeing JW14 leave would be. No. There's only 3 forwards I would keep above Williams (Kopi, Carter, Toffoli) but I'm admittedly biased here.
McNabb, McBain, Schultz, all the new guys back there have been better than I thought they'd be, Bainer especially. Martinez and Doughty have been excellent, no surprises there. Okay Schultz isn't great, but Matt Greene is a liability all the time, even if I do like what he brings when the play is dead.
Greene is great after the whistles, he's a presence out there but he blows assignments consistently. MG leaves gaps between him and his man that are too big for a slow-handed tugboat to make up AFTER his mark has the puck. He doesn't even bat pucks away these days, terrible puck-stick handeye.
I would try to see what I could get for a package of Mike Richards and Green(siev)e, with a draft pick for a slightly below elite level defenseman, like say Klein with the Rangers or Shattenkirk in STL. DL knows something has to get done, but it's not dealing Williams for a guy who last year would have been the 4-5 guy on the D-corps.
