I think that this deadline went according to management teams modus operandi. I have the impression that they try to make moves so that they do not sacrifice too much future success for short term investments. Meier would have been good short term solution, but it would have come with pretty hefty price. But for me Meier's worth was now at his absolutely peak value and generally it is not beneficial to pay peak prices. For example, I would argue that Jesse Puljujärvi will bring like 95 % of what Tanner Jeannot will bring, but because he was "distressed asset" the price was fraction of what Lightning paid of Jeannot. There could be more risk involved with Jesse than Tanner, but I think that there is also more upside. And re-signing Jesse will be a lot cheaper than re-signing Tanner. So Hurricanes pay a little more cash today, but less next year if they want to bring Jesse back. I also think that it was Meier vs. Pacioretty and they decided again that they suffer a bit today to get better investment tomorrow. To me Fast is also in the end of plateau phase of his career and starts gradual down swing and Jesse is expected to be replacement who is still at up swing of his career just like Kotkaniemi is growing to be Staal replacement.
For me Gostisbehere is also in plateau phase which will last for few years, but the price was so low and frankly the needed level for upgrade (DeHaan) was also quite low, so with that price it was beneficial.
If we think this season, the upgrades (third pair defenceman and fourth line winger) were small, but Hurricanes also did not sacrifice much of the future. Maybe Hurricanes odds this year did not improve much, but maybe odds actually improved next year, since other teams in Eastern conference sacrificed a lot more. And I am hopeful that Hurricanes get more Pacioretty like distressed assets in the summer.
