The trade is not made without the $10M "savings," IMO. it was an essential part of the trade.
I also think it was a valiant attempt to solve the 2B problem we have had since Pedey got hurt. It's not like 2B was not an issue. Had Grissom filled that void, the trade would make more sense, right now,
Since 2017, we have had 20 second basemen with over 44 PAs and 16 over 82.
2017>today 2B PAs only (OPS)
544 Arroyo .739 (not even a full 650 PAs by one player!)
492 Nunez .691 (mostly from half season in '18)
487 Holt .739 (probably our best 2Bman)
457 Pedey .755 (was a drain on the budget)
396 Story .737
304 Kiki .901
263 Valdez .646

No doubt, the rotation was a major concern, last winter, and we can now see why, but 2B was, too.
The swap out from frail Sale to Gio did make some sense, at the time, when you also factor in the idea that they felt they were solving the 2B problem.
