The A's where right there almost every year while spending 20% of what the Yankees did. It worked pretty darn well IMHO. If they could have spent real money, they would have won a handful of WS.
But they didn't. The entire point is to win a World Series and the A's, in that time, only won 1 playoff series. Hell, no team has won as cheaply as the 1993 Phillies with a team full of has beens, never wases(?), and castoffs that got hot, stayed hot, and ended up in the World Series and came close to winning. But in the end, they didn't win. It's takes home grown talent as well as key free agents to win a championship. Moneyball is a good concept but in the end, all they were was competitive and nothing more. No World Series appearances and no World Series championships.
As for this guy and the Browns, I'm sure the Browns fans would take in a Voodoo priest if it would do any good.
