I'd agree it's pretty tenuous for this year especially. Our dev guys would have to look at him and think there are things he can change.
But i will make a case for next year especially.
Firstly, he's a good fit for how we play. By most metrics he's the best 3B in baseball this year. We value defense. He has a below average strikeout rate. Not a great barrell rate but better than say clement. And a 110 max EV. He also has a pretty good z contact rate. If you could get him to 100 wrc+ he's a valuable player.
If Bo goes, you could have an infield of vlad, clement, gimenez, hayes which should be the best infield defense in baseball. Outfield of Santander, Varsho, Springer. Barger would get a lot of time as two outfielders and vlad would be DHing regularly. I'd also try to get hayes to play second sometimes to get some platoon matchups and barger at third.
Finally, he costs a similar amount to straw annually so he is cheap.
