The Philadelphia Phillies approach each and every season as though anything short of a World Series title will be a bust. Given the high pressure environment that Philadelphia sports fans bring to the table, that isn't a bad philosophy to have.
Over the last couple of seasons, that seemed like a realistic goal. The Phillies had one of the best starting rotations in baseball, a solid bullpen and an offense that could score some runs—if they could stay healthy. The best and worst case scenarios were fairly easy to determine.
Moving into the 2013 season, those scenarios have become a bit more clouded. Given all of the variables that stand between this club and a potential parade at the end of October, calling the '13 campaign "World Series or bust" may not be fair to any party involved.
But the one thing that remains constant through all of those variables—this season more than ever for the Phillies—is that this club is going to have to stave off some of their worst case scenarios if they want to be successful.
This slideshow will serve as a primer for the upcoming season, outlining each player's best and worst case scenarios in an attempt to determine what needs to go right and what can't go wrong if the Phillies want to contend—and win—a World Series title this year.
