Except I don't think the Yankees are going to regret overpaying for guys anymore. Any team with CC, A-Rod, Teixeira, Cano, Jeter and Rivera will be in playoff contention. They can afford to just throw a 5 year, $70m deal at him and it won't impact them at all.
Remember how this past offseason how their fans (Jacko, Gom) were touting that their payroll would actually drop? It didn't, but they don't care.
Very few people make the financial advantage argument very clearly, and I think too many Sox fans just let it go. The fact is that this team DOES have financial constraints, whether Jacko or Gom or a700 want to believe it. Yes, they have a shitload of money, OUR money (I pay for mlb games on my computer, I go to some games, etc.,) but that doesn't mean that they should let all financial considerations go out the window. NY and BOS are completely different markets, no matter how many fans the Sox have it won't match the NY Metro area, and their worldwide drawing power.
