I won't be upset because:
1) It's better to send him down than risk losing depth. Even if that depth isn't great, it's still better than the other options in Hartford.
2) Mancini can be brought back up at any time, and likely will play more in the NHL this year than the AHL.
3) We are likely to make the playoffs regardless, and I'd bet money that Mancini will be in the lineup when the games really matter.
Not every choice is black and white. It's not always about player A being a better option than player B. There are other considerations that factor into the decision.
Would I prefer to have Mancini stay with the team and play every game? Sure. But what I want isn't necessarily what is best for the team as a whole.
The only way Mancini doesn't get sent down when Lindgren is back is if Drury believes he can get Ruhwedel through waivers. Ruhwedel is making the minimum on a 2-way contract, which suggests no other team was willing to give him a 1-way contract. It may be then that no team would claim him. We'll see if Drury is willing to take that chance.
I don't think Drury or Lavi has any particular love for him. He barely played after we acquired him last year, and he has barely played this year so far. It's clear that they prefer Mancini. It's just a question of whether or not they will take the risk of waiving Ruhwedel.
