Wow!! This is one of the most outlandish trades that I've seen here yet. You expect Winnipeg to give up two d-men prospects (one who is going to be outstanding), AND add two meaningful draft picks to take on an aging defender whose skills are diminishing quickly and is earning $6.75M a year for the next 5 years? Whoooo!!! Everyone in Winnipeg would lose their jobs the day that trade happens.
On top of all that, McDonagh controls his destiny, and his destiny's destination is most certainly not Winnipeg.
Like I said to another comment about McDonagh it Does not have to be to Winnipeg, Chicago also has the defensive prospects to make a deal. But, McDonagh is from St. Paul Minnesota, so Winnipeg would take him close to home and that is something a lot of older players want (see Duncan Keith).
Also I would argue that Niku is not really a A or B prospect, I would call him a C prospect at best, Winnipeg completely restructured their Back end this year and he still could not find an every day role on the Team. He was a 7th round pick 6 years ago and will be 25 years old by the time next season starts and I think his ceiling may be a bottom pair d-man. In all I would say Niku's value is minimal at best right now and he wouldn't be an integral part of the trade.
Secondly, I don't know if you can call a guy who's averaged 24min a night over two cup winning runs in the past two years diminishing. He was never the greatest or fastest skater, he was always solid positionally and added tons of value in his own end while chipping in around 0.5ppg with NYR and his first year in TB, and we've seen multiple examples of how slowly elite d-men of this archetype can age (Chara, Weber, Edler (to a lesser degree)). Yes his point production may have fallen off with TB the past few years but he's been asked to play a different role, one that is more defensively oriented but he has still excelled. I think if he goes to a different situation where the expectations of him are different he could revert back to closer to 0.5ppg that he was averaging up until 2 years ago.
Now onto Stanley, who you say is going to be outstanding, yes he could be, but he also could just be an average every day NHL defenseman. He is 23 heading into next season and is coming off a season where he averaged 13min of ice a night and put up 4pts across 37 games and 3pts across 8 playoff games where he averaged 14min a night. He has never really been a huge point producer on the back end during any part of his career so far. He has elite size but that's really all we know about him, will he turn into a Chara? likely not. Could he be another Oleksiak where he plays 18-20min a night and puts up around 20 points a year, I'd say that's the minimum that the Jets are hoping for. Could he be an Erik Cernak type, playing ~20min a night putting up around 30pts a season yeah potentially. Could he be somewhere in between the 3 of these? I'd say that's likely, but I wouldn't say he's for sure going to be an outstanding D-man.
If your problem with the deal is you think its too much for McDonagh then feel free to take out Niku or the 3rd round pick but I honestly do not believe the trade is that far fetched when you look at all the factors including Winnipeg's needs on the back end, and the potential that McDonagh may find being on a competitive team that is only a 7h drive from his family home in St. Paul attractive at this point in his career.
