First, he's not just a "defensive center". He's a defensive center that can get you 60 pts. That's top line offensive points. Second, you don't have a "lot jam" Stall, Rask, and a bunch of prospects isn't a "log jam". Third, O'Reilly was also a 65 point winger. Forth, O'Reilly worth more then Hanifin.
I'm not sold on ROR being offensively much better than Jordan Staal for us, at least as long as Bill "my gameplans are where scoring goes to die." Peters remains the coach. I don't think the difference is talent as much as the stifling crap BP runs.
Staal, Lindholm, Aho, Rask. Logjam. That's not talking about the specs...we have 4 middle-6 C's already on the roster and Aho & Necas might have 1C upside themselves.
Worth doesn't exist in a vacuum...we need what ROR brings less than most buyers. He's a luxury, not a need, and we'd likely pay less than other buyers for that reason.
Yes, if we're moving Hanifin, I'm looking for something around Mittelstadt...it's a better fit for our needs and core. Trades are things that have to address both teams needs. You need a D with 1D upside; we need an offensive dynamo.
