I'm not judging their ability to hit LHP off of 100-150 PA sample sizes of last year. For their careers, Farmer has a 100 point OPS lead on Polanco. A strong platoon with Farmer facing LHP and Julien facing RHP is all but guaranteed to outproduce Polanco because of the platoon advantage. Do you think it's unreasonable to be comfortable platooning Kyle Farmer? Who said Polanco will "fall off a cliff"? I don't think it's unreasonable to look at his recent injury history and coinciding drop in production and feel comfortable saying that Julien, who is already a better hitter, has a pretty good chance to be more productive.
I meant PA and typed AB, my bad.
Edouard Julien spent close to 2 months in the minors last season and they didn't give him regular playing time in the first half. He had 487 PA against RHP across both levels. FWIW, 23 players in the league faced >500 PAs against RHP, Mookie did it in 140 games.
The Twins had 1 player clear 500 PAs because the vets were largely injured (including Polanco fyi) and they didn't give the young guns regular playing time until June/July.
The team lost little to no production at 2B, gained a 7th/8th inning setup arm, and will assuredly need some innings in the #6 rotation spot from an 4-5 ERA starter - which is a lot better than most teams get from that position. If you think that's "the hottest of takes" I'd love to hear you explain why they will be *so* much worse after the trade.
