I think DL will try to trade for an LW at the deadline but not Jagr, way too expensive for a rental and I think the pace of the Kings game and how hard they push it would affect him unless he was on the 3rd line with sheltered minutes.
I think Dl wants a more permanent fix for that side and I'd love to see Vanek with Kopi (he wont stay in LI, so they'll trade him by the deadline) but the price would be too high, same with Moulsen, I'd guess. There will be a few good options there and teams selling, esp in the Metro division, lots of golf bound teams there.
Fleischman might be a cheap option, his price tag wouldn't be as high.
I think DL wants to improve that LW but it's just a matter of how savvy a trader he can be and how patient.
Maybe he can call up his buds Homers and Hexy coerce them to deal Matt Read.
