One big problem is is that it isn't often that these true elite players like Fielder or Pujols hit the market, so when these massive contracts have been handed out in recent years, it has been with bad results. Soriano, Zambrano, Wells, Rios, Zito, Rowand, and Peavy are some examples that come to mind, and Werth and Dunn look like they're on their way. Their are also a good number of big contract guys like Holliday, A Rod, Sabbathia, Miggy, who have turned out well for their teams too, but their have been a significant number of big contracts gone bad in recent years, so teams could be getting very gun shy. This being said, when you have the chance to sign one of the elite players in the game, and not just a big name in a bad market, you need to take it, especially when you are in the situation the Cubs are in.
