In general trading a 130 middle of the order bat/OF for a volatile RP coming off one good season isn't something I like. Splitter is a tough pitch to consistently command.
I get the deal analysis for 2023 - Teo was worth twice the fWAR of Swanson in '23 in a down year, but the Teo money savings allowed the KK signing he put up 2.8 WAR plus extra Swanson control. One year window that makes total sense.
The FO made a move to punt Teo and went to a D and pitching pen focus. "Break up the barrio".
They also punted LGJ + Moreno same off season. Moreno has + 2 years of control over Varsho and 4 years younger. Moreno won a gold glove(I know I know...GG) for DRS and Varsho is elite on D. LGJ alone and Varsho worth the same WAR in 2023. Dealing Moreno will be felt hard in '25 if we have to overpay to keep Jano, or he walks. When they moved Moreno Jano needed to be extended.
I don't think you can look at one move in isolation. Thus far, the FO strategic elite pitching and D directional change hasn't been that successful. Less W's in '23 and 1 run in 18 innings in the wildcard. A lack of power overall thats been worse in '24 thus far as our team wRC+ has dropped.
There is an alternative path that could have been taken where we extended Teo 2/3 years + option in '22. He was coming off a 3 WAR season, spotty D, and hitting a couple HRs in Game 2 vs SEA in the wildcard. But his stock wasn't soaring so it could have been a reasonable deal. We'll never know. Hindsight is 20/20.
