Very true. Just saying that his good year vs a Biggio good year is pretty significant for a team that's trying to get over the 95-ish wins threshold.
By no means is trading for him needed, but to think that an offer of Pearson, Kirk and Biggio would even come close to getting a deal done is pretty silly. (not your words, i know). Plus, when talking about this trade vs the Olson trade and trying to compare... gotta remember that different teams value different players and prospects differently, not to mention that Olson is a 1b, vs a plus defending 3b (or 2b i guess) with roughly equal offensive output. That's a pretty big difference.
