This year our top 4 starters put up a weighted average FIP of 3.68, while the remaining starting games we got out of the 5 hole was an FIP of 5.30. So basically we have a pretty big outlier at our 5 starting spots as can be seen here showing production from each starting spot 1-5.

The top 4 guys posted a 3.68FIP like previously posted, and that reesulted in a record of 51-30. The 5th starting spot (and all those that filled it) posted a 5.30 FIP which resulted in a record of 9-19. If you were to supplant the FIP that the 5th starters posted with a reasonable # like 4.24 then the should have an expected winning % out of the 5 hole of .516%. Or 15-14.
If you look at Tampa they got a record of 57-36 (.613%) from their top 4. The Jays record is actually better at 50-31 (.629%). But Tampa's 5th starting hole + replacment pitchers (they only had 7 GS by guys not in their top 5) had an ERA of 4.10, and a 19-10 Record. Compared to our 9-19.
So basically I'm thinking if we were to get consistant production from our 5th starter next year, and Tampa looses Pena, Soriano, and Crawford (9.5 cumulative WAR) then we could potentially be mid-90's for wins and have a crack at the wild card vs. them. And I think we do have guys capible of putting up <.4.24ERA's next year from the 5 spot like Litsch, Rzep, Drabek etc...
Thoughts?
All other things being equal that would move us into low-mid 90's for wins.
