I guess I'd ask what the alternative is. For example, take out santana, and replace him with the next guy in the minors. Or take out a RP and give those innings to the guys that produced negative value. People always point out the end of contracts being bad, ignoring the beginning being good. People point out that players get hurt. But they rarely point out what happens if the team had to use the next minor league player they are willing to use. So, what's your proof that signing one great free agent is bad? Not every. Not a lot. One. Because if they don't add good players, they have to play not good players instead.
