After the New York Yankees signed the three biggest free agents on the market, Milwaukee Brewers owner Mark Attanasio sent an email to Bloomberg calling for a salary cap: "At the rate the Yankees are going, I'm not sure anyone can compete with them. Frankly, the sport might need a salary cap." He added that "I paid $220 million for my team; now they get three players for $420 million."

Under a salary cap system, teams would be limited as far as how much they can spend on player salaries each year -- the idea is to allow smaller-market teams to be competitive.

But in an interview with CNBC, Scott Boras -- the controversial super-agent who represents Mark Teixeira, Manny Ramirez and many others -- explained why he doesn't think baseball should have a salary cap. Of course it's a pretty self-serving argument but here's what he said: "I'm not sure what a salary cap does other than it prevents choices."

Of course Scott Boras could sell a champion sailor to a guy in the desert, but he actually might be onto something with this one: The free agent frenzy of out of control spending adds a "Hot Stove" season to baseball that others sports lack. And for all the talk about big budget teams killing competitiveness, the two teams that made it to the World Series ranked 13th and 29th (second to last) on the list of teams with the biggest budgets.
