I disagree. Hoffman is a flawed but useful first liner, RNH is a second liner. Hoffman produces more and costs less. RNH plays a position at which the Sens have relative strength in their prospect system whereas there's noone around that could feasibly replace Hoffmans contributions any time soon. Trading Hoffman for RNH leaves our LW depth at: Dzingel and nobody. As it stands second line center is a serious weakness for next seasons but chances to fill it internally are much better than materialising an adequate first line LW out of thin air.
Both Duchene and RNH can play LW, Duchene more so than RNH. Duchene is arguably better at LW than he is at C.
Our prospect center depth means nothing until they actually develop to that point. At which time, we could trade RNH for futures, or help in a different position. Unless we get really lucky, there's no prospect in our system that projects to be an NHL 2C next year.
Not acquiring RNH leaves our center depth just as bad if not worse than trading Hoffman leaves our LW depth.
With RNH, we get a player signed for 3 more seasons versus just 2 more seasons. With Hoffman signed at only two more seasons, which if we cannot extend him amounts to only 1 more season since there is no way this team will be in a position to give up on the 1st round pick they'd get for Hoffman in a trade and let him walk for nothing.
If we were a run n' gun team, I wouldn't do that trade. I think Hoffman thrives in that kind of system. With our current coach, assuming Boucher is staying, RNH is a lot more useful of a player to have. Hoffman hasn't been as good under Boucher as he (maybe ironically if they didn't like each other) was under Cameron, so I think RNH could replace a good chunk of Hoffman's production while giving us versatility down the middle and being a stronger overall two way player. He is also signed to what is a more favourable contract for us (3 years @ 6M vs 2 years @ 5.65M), and given the type of offers we heard of for Hoffman at the TDL (Kyrou+2nd) RNH probably has a similar value in futures if it ever comes down to having to sell him off like we've apparently at least explored with Hoffman.
With that said, guys like Bob McKenzie and Bruce Garrioch are playing down this potential trade, so the good news for anybody who doesn't like it is that it might not be likely to happen.
