For what it's worth, we were lacking a 2nd line center for all of what, 60 games? Most of which was in a season we had written off? We acquired Turris early in the year after moving Fisher. Fisher was also 30 yrs old at that point, so you could make the same argument about him more likely to regress than improve (though he started off better than Kelly).
As for the return for Vermette, it was at least an attempt to fill a long time need for the team. It backfired, but the idea was right. Move an expendable asset (Vermette wasn't cracking our top 6) for a position of need (goaltender graveyard afterall). The 2nd round pick has panned out pretty well, so I'm still ok with that trade if we ignore the benefit of hindsight.
Edit: trades that we should be pissed off about are the ones that made no sense from the get go: Havlat for a bag of pucks, Laich for a redundent aging Bondra, Commodore (I liked getting Stillman, wish we re-signed him), Campolli made a bit of sense (from a team need perspective), but imo, if you're going to give up a 1st, aim higher and add a bit more.
