I see both sides of things here.
On one hand, baseball is a sport that this can actually work out quite well for the Sox. They get some prospects and now they can directly go out and spend all that money this offseason (or next offseason, or whenever) to directly get new superstars. That doesn't work in sports like basketball that has a soft salary cap.
On the other hand, I think the Sox woes are somewhat exaggerated this season. Don't get me wrong, it's been painful to watch at times, particularly the past week or so; however, if they had had better health, I could see them at the .500 mark right now, contending for a wild card spot. If they had better health and played in another division besides the AL East, I could see them contending for a division title.
Now that doesn't mean they aren't a flawed team, but it also doesn't mean the sky is falling quite as badly as some people might think. As much as Beckett has p---ed me off this year, this fluctuation in performance is quite normal for him, as he's alternated having great years and bad years for the past 4-5 years now. It's entirely reasonable to expect that not only will he do well in LA, but that he could've done well here next year too. Carl Crawford was also showing signs of bouncing back this year.
All that said, I do like the idea of redistributing the money though. Dan Duquette always talked about wanting to invest money in the middle of the field (SS, 2B, CF, P, C). His reasoning was that those positions were the hardest to get offensive power out of (and pitching is obviously very important). In other words, it's fairly easy to find an average 1B who can hit 20 homers; it's not so easy to find a SS who can do it. Same with RF in comparison to CF and so on.
So as much as I love Gonzalez, I do like the idea freeing up some of that money (and the Crawford and Beckett money) to reinvest in pitching and perhaps finally get a SS to replace Nomar.
