Should the Pirates explore a move by the waiver deadline?

The title of this post is somewhat misleading as we return to baseball as of course they should explore a move to bolster a suddenly fading Pittsburgh Pirates team,the better question is should they MAKE a move and if so at what cost?

The Pirates have won just three of their last ten and have lost the first two of a series against the Cardinals in a set that could have placed the Pirates in a stronger situation for the wildcard (bleech) spot(s).
The losses have moved the team to three games behind St.Louis and makes tonight's game extremely important.
Pittsburgh has tried to add through waivers,per the recent addition of Hisanori Takahashi from the Angels and released Erik Bedard in order to reintroduce Kevin Correia to the starting rotation,so the Buccos are attempting to shuffle the deck a bit in order to catch lightning in a bottle.
Bedard has been a disappointment and I can see the logic in the release,but I fail to see any improvement in moving Bedard out and the mediocre Correia in.

The question still remains-Should the team make a major move for a bat or arm,assuming a major player would fall to them on the waiver claim list?
I still say No,unless the price was minimal.
The Pirates are a team that seem to have caught some fortunate breaks,had the odd player playing above their true level and were able to have caught a blossoming superstar in Andrew McCutchen burst free at the right time.
In my opinion,that is a team that not only was made for a late season drop,but one that is more likely than not to disappoint next season due to unrealistic expectations.

I am not against a addition that costs money or a minor level prospect,but I am against a strong move that costs a future building block for a season that will prove to be fun and entertaining season that was fated fall short for one reason-it simply was yet to truly be the Pittsburgh Pirates time....
