In the positions of need, you missed a few. C-Jeffers is league average at best. (But hey, that IS MLB caliber!)
First- No one on the roster can field it.
2B- Unproven.
3B- Lewis has been a liability the past 1.5 years.
SS- No one on the roster can field or hit.
LF-Wallner is league average, but you want him to DH/1B? He’s one of 3 MLB players on the squad, but in LF.
CF- Only above average position player on the team- when he’s healthy…
RF-No one here can hit.
DH-Bell, I guess?
Where is this “Core” they’re supposed to be building around???
