I avoided the ERA-/ERA+ metric because pitchers do not become more talented due to defenses behind them. But it’s not like one year of fWAR isnt without flaws either.
The bottom line to me is - the Sox can use this off-season to upgrade their SP, but there are multiple ways to go so beyond the fictional #2 starter. The Sox will have 11 SPs on their 40 man roster once the off-season starts (a number that includes Houck because he has to be there from December through March) so they can part either a pitching prospect if necessary, although loving one or two to the bullpen is probably smarter.
Of these 9 pitchers ( not listing Houck or the recently activated RHP Luis Perales), the ones I would consider trading (in order) are:
1. Harrison
2. Crawford
3. Fitts (but I prefer simply putting him in the bullpen)
4. Dobbins
5. Bello
6. Sandoval
7. Tolle
8. Early
9. Crochet
Adding another starter isn’t tantamount, but it wouldn’t hurt.
But rather than calling for some sort of co-ace, another (smarter?) strategy is build up the bullpen and just add an innings eater. It doesn’t agree with anyone postseason plans, but starting pitching in the postseason is different anyway and often includes quick hooks to the bullpen.
I kept reading about Bello’s “awful” start, but 2 ER in 2 IP isnt horrible. Heck in the Cubs-Brewers series, that would be elite…
