That's what Fox is buying. Sure, they would love a higher rated series, but they were able to promote all their shows and can boast they were number one last week. It's a win for them.
No surprise. The Series was one-sided, nobody cares about the Rays, and the weather played all sorts of tricks. It would have been amazing if this Series had reversed the long-term downtrend.
At least the Red Sox got good cable numbers for the ALCS.
