Please give me a solid example of how signing a big FA fish has ever helped a team move forward from a crummy situation where the in-house talent isn't good enough, the farm is mediocre at best, and the financial situation is near the upper limits.
Angels fans were probably pretty happy when that team signed Pujols, CJ Wilson, and Hamilton, right? That's THREE big fish, and all they did was help the boat sink quicker.
AA needs a bucket, not a lunker. Start bailing water (eg. making responsible decisions) and maybe the SS Anthopoulos won't sink.
