Let's briefly travel four months into the future.
It's the last week of September. Your team is in a three-way tie for the final playoff spot with five games left to play. Based on what we've seen through one quarter of the season, which starting rotation would you most trust to take you to the promised land?
That's the thought process behind these rankings.
Whether it's the same thought process that Rick Weiner had when he did his rankings prior to spring training is unknown, but his rankings are the benchmark used when referencing a rotation's previous rank.
Where applicable, players on the disabled list are referenced and taken into consideration, but this is primarily focused on starting rotations as they stand today.
All statistics are courtesy of ESPN.com and FanGraphs.com and are accurate through the start of play on Wednesday, May 15.
