I specifically got bummed with the Poni deal. Look around pages 4-6 of the other trade deadline thread.
Dealing guys like Lebda doesn't count, IMHO. Of course I wouldn't mind him being moved, but you made it sound (in this thread) like you wanted to dump picks/prospects, rather than guys like Lebda. Losing Abdelkader wouldn't be the worst loss, but it'll also be interesting to see if he can become a Draper-esque player in the next few years.
Now, losing guys like Lebda and Abdelkader plus a pick to supplement some goal-scoring depth up front probably isn't going to make or break this season. I'm not going to get into Holland's comment about Franzen, Lilja and Kronwall being our trade deadline acquisitions, but I will say that the guys that needed to step up in their absence will be more effective now that the pressure is off and they're playing against lower line talent.
Lastly, while it's obvious depth is one of the most important components to winning a cup, I'm just not sure one guy like Poni is enough to equate to much of a difference at all.
Now, the Williams signing.....I agree with. Injured or not this season, I don't think he would've done anything worth his $1.5 million like Bert has. Now that being said, we also need to keep in mind that its not as simple as his $1.5 equaling a $5 million player. Adding a guy like that doesn't just cost money, it cost prospects/picks that the Wings really don't have a ton of right now.
