94 points from a 3/4 healthy roster in Detroit was in the realm of possibilities. They were in a playoff spot until the end of february when Yzerman traded Bertuzzi (injured most of the year) Vrana (did something stupid to get himself traded for nothing) Sundqvist (forever missed!) and Hronek (was actually playing pretty well.)
If those trades weren't made Detroit wouldn't have had such a miserable finish to the year and would have been pretty close to that 94 point mark.
This year Detroit is going to be adding...
Edvinsson (whenever his shoulder is fully rehabbed)
Sprong (Slight downgrade compared to a streaky Vrana when looking at their careers)
Compher (MAJOR upgrade on Suter)
Kostin (MAJOR upgrade on Erne)
Fischer (MAJOR upgrade on Chiasson)
Gostisbehere (About equal with Hronek)
Holl (MAJOR upgrade on Lindstrom despite what Leafs fans will say)
Petry (MAJOR upgrade Hagg despite what Habs fans will say)
DeBrincat (MAJOR upgrade on Kubalik despite what Sens fans will say)
Reimer (About equal or worse than Nedeljkovic)
Lyon (MAJOR upgrade on Helberg)
It's also important to remember that Seider and Chiarot was a terribad pairing and we're unlikely to watch that for 40 games again. But when Seider was put with Walman, a no-name throw-in on the Nick Leddy trade, Seider/Walman became one of the best pairs in the NHL near the end of the season.
A fully healthy Detroit team playing solid defense and getting average to above average goaltending might get 97 but I don't think something between 90 and 95 isn't crazy after factoring injuries in. Their depth and farm system this year will help mitigate points lost that they couldn't handle last year. For instance, having Rasmussen (top 6, knee), Fabbri (top 9, knee), Bertuzzi (top line, hands then trade), and Vrana (top 6, idiocy then trade) out meant Detroit was missing 4 wingers from late February until the end of the year. It would take a lot of broken mirrors and walking under ladders to replicate that kind of bad luck.
