1) No one is going to add 8m in Trouba salary unless bad salary going back.
2)I would guess there are less than 5 teams that would be willing to lose their number 3 defensemen in the ED unless clear exception (A Piet as example for Vegas). Trouba is not a clear exception.
3) Trouba trade gives the rangers a 20-21 d lineup of a rookie and 3 of Smith, Johnson, Vietto, and Tony D. That makes the Leafs defenses of the teens look like the Wings of the 90's in comparison.
But other than that....
Other than that...
any deal I said to this effect needs to be updated, b'c it contained 2020 picks which no longer applies. That said,
The rationale for DET to consider this is not to take on JT and his $.
The fully adequate incentive is to express acquire assets needed to have a legit team immediately. This includes but is not limited to
Chytil = 2C
Geo = starting G [even if you insist in saying 1a-1b, he'll start in hockeytown]
upgrade of picks\
speedy Howden for 3C
that w/Trouba is enough to justify surrender of Seider, who projects as Hedman lite, but vs that benchmark we don't know if he will be equally good, not as, or a possibly even better.
Also Seider has not been promoted yet. [CF has him as 'non-roster']
Is he ready for start of upcoming NHL season, whenever that is?
If not, for whatev reason, NY can handle that esp on right side.
That's not a big deal as he is close to, if not actually ready, but NY help would be of immediate use to DET.
