The National League East has become much more powerful and balanced over the past year due to acquisitions and the maturation of highly touted prospects.
The Miami Marlins will have possibly the most balanced staff with the acquisition of the durable and competitive Mark Buehrle, as well as the volatile but suddenly motivated Carlos Zambrano.
The Atlanta Braves will have the youngest rotation, but they are certainly not lacking on quality arms despite their deplorable September swoon.
The Philadelphia Phillies still have their embarrassment-of-riches staff topped with three arms that would be the aces on nearly every club.
The New York Mets feature the biggest question mark of a rotation, but the biggest upside pending full health from all of their arms.
The ranking will be based on past performance, age and future predictors of performance.
