Clement and Giminez are going to provide elite up the middle defense, if they have league average bats they should combine for 6~ fWAR as our 8-9 hitters. Not concerned about them too much. Add in Varsho and Kirk, the middle of the diamond is freaking top notch defensively, and Straw is always kicking around as that stud outfield defensive replacement.
Santander needs to bring the big Taters bat though, It's pretty important, and will leave a big hole if he repeats last years debacle.
The biggest wild card is obviously Oka, on both offense and defense.
The good news is the roster has tons of depth and versatility to cover for underperformance and/or injury. And the pitching looks oh so juicy on paper.
