grabo hasn't been much better than weiss. scored 4 points in that one game (first game iirc) but outside of that, he hasn't been that good. flip has been much better. and based on reviews, derek roy.
though with his deal, it would be much better to have him than weiss.
I think the Wings wanted some long term stability in the #2C position & IIRC neither Roy or Grabovski were really willing to go long term. It left Weiss & Filppula for our needs & we had already tried Filppula there & it didn't work so it left Weiss who we were already high on, IIRC the Wings were looking at trading for him before he got hurt last year.
While he hasn't been effective offensively the past couple of games Weiss has looked realgud defensively to me. It seems like he is getting used to the system & if he can finish the year with 40-50 points in the last 70 or so games I'd call it an okay year for him.
The TSN crew was also talking about the hard time Weiss is having adjusting to Detroit and that when they talked to Babcock earlier in the day that he said he wants Weiss to reset and just get comfortable playing the system, that right now the points don't matter just get used to the system & the points will come.
