A few thoughts now that I've digested this a bit more:
- I think something that probably played a factor here is stability. Not year-to-year, but game -to-game. LF, RF, and 1B are all holes, and at least one is likely to be a platoon. Morales is a switch hitter with no platoon split. He's someone that Gibby is going to pencil in 3rd or 4th every day, regardless of who's on the mound. There's value in that in a lineup that might have a lot of moving parts.
- He can hit. A wRC+ between 110 and 136 in 6 of the last 7 years, with the only exception being in 2014 where he waited until midseason to sign and never got going. Projections are probably giving more weight than they should to his 2014. Also, as GD alluded to, he relies on the HR to do damage and Kaufman really wasn't a good park for his skill set. I'm willing to bet that internal projections have him closer to a 120 wRC+ next year than the 109 Steamer has for him.
- There has been research done on the 'skill' of being able to DH without seeing your numbers drop, as a lot of players don't like doing it, and perform worse in the role. I wonder if the team buys into this kind of thing and saw value in Morales as a guy who is absolutely fine swinging 4 times a game and sitting out the rest.
Overall, I don't love it, but I'm fine with it. I wish it were 2/22, but I think Morales will be a nice addition to the lineup in the short term. He's not Edwin, but he can hit.
