FP'd for the sake of a new thread...if someone else has something, I'll take it back down.
Using FIP = (13*HR + 3*BB - 2*K)/IP +3.67, White Sox starters have delievered the following 2/5 the way through the third turn of the rotation:
And for kicks:
Marquez: 7.50 (AAA - per First Inning)
Contreras has been near replacement level through his first two starts, but the rest have been quite good. An average offense is going to win a lot of games with starts like these. If/when Colon and/or Contreras go down for whatever reason, Richard and Carrasco can probably split starts/piggyback. Marquez needs to stay the hell away from the major league team, as should the rest of the Charlotte rotation for now. Reinforcements still aren't coming. Surprise.
I matched the constant to RA rather than ERA, which makes average about 5.00. Replacement level is like 6.4, but that's more of a best guess. You can project this out into Wins Above Replacement pretty easily, since FIP is denominated in runs per nine:
Runs Above Replacement = (FIPreplev - FIP)/9*IP
Wins Above Replacement ~ RAR/10
