If anything, Braun's extension seals the deal on Prince Fielder's departure at the end of the season. The Brewers, while a much more successful franchise than during the years Bud Selig owned the team, are unlikely to want to commit nearly $50 million a year for two players for half a decade, years ahead of time.
The Brewers made the right decision in choosing Braun over Fielder. While Fielder's one of the most feared sluggers in baseball, it's hard to see a player with his frame aging gracefully in his 30s.
However, the Brewers probably made a mistake here as this wasn't a contract that the team needed to sign. It does tell the fan base that the team's not going to give up on signing its own players, but a nine-figure commitment is a pricy way to do this.
