Re: Arthur Rhodes: at what point do we try to sign him for 2011?
After the season. He could get injured. His performance could decline. Very few relievers are so reliably special that they need to be signed to multi-year deals. It's great that he's been effective so far at 40, but the end will come sooner rather than later and I'd prefer to not be on the hook when that happens.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
