It's justified with the money aspect. Like it our not, this was purely a money move by a cheap owner.
Maybe it was money motivated, and the dollars certainly point to that, but at least in the short term Ottawa is a better team with this trade.
Zibanejad is a 20/50 centre who is frustratingly inconsistent. He is a slow starter who shows up to training camp fat and takes a while to get going. The odds of him being better than Brassard when all is said and done aren't high. But of he does put it together, he could be a game changer that makes Ottawa look foolish for trading him.
NYRs save cap space this year, recoup a draft pick, and maybe save a bit of cap going forward. Ottawa saves salary with a cost controlled player who is likely to take a home town discount after this contract.
They are DIFFERENT types of players. Ottawa needed a left handed skilled top 6 C. People who don't watch Ottawa games might wrongly perceive this as only a centre for a centre.
As much as non-Sens fans perceive Ottawa as an inconsequential non playoff team, they are trying to win. This is a good move in that direction and age doesn't matter here. Brassard is still young, and no GM is going to neglect making their team better over the next 3 seasons in fear of what'll happen in six seasons. It isnt like Ottawa is trading an 18 year old blue chip for a player nearing retirement.
