I totally agree, and with Nate, Wacha and Strahm off to free agency, we have a big task ahead.
We also have some huge question marks, concerning health, with Sale, Paxton (option?) and Taylor- Houck and Whitlock to a lesser extent. Which Barnes shows up is another question. Many holes to fill.
I'll slot Houck & Whitlock in the pen, but one may fill a rotation slot by opening day:
SP1 ____
SP2 ____
SP3 Sale/Paxton
SP4 Pivetta
SP5 Bello
SP6 Crawford, Wink, Seabold, Mata, Walter, Murphy, TWard
Closer ____
RP2 Whitlock
RP3 Houck
RP4 ____
RP5 Schreiber
RP6 Barnes
RP7 see SP6 or Taylor, Kelly, German, Brasier, Danish, McGee, Reed, Ort, Politi
