It is definitely possible Murphy is more like a 780+ OPS player. But 780+, with elite defense and 28 years old vs. TD at a 690 OPS, pushing 35 years old and inferior defense still makes this a no brainer. Then there is the hard to quantify point that Murphy has not gotten a chance to "play himself out of his slump" and its totally reasonable to believe its had a meaningful impact - not to mention, hard to ignore the mental aspect of "pressing" knowing your playing time is just continuing to get worse and worse. Overall though, as noted, its bizarre to have gone all in on him, traded our best trading chip, given a big extension and then been ok with him being a part-time catcher for most of the season.
The other concern is TD just flat out sucks now offensively - and unlike Murphy, TD's sucky stats are on a full-year basis. Point being, he just can't be a "co-starter" - we need Murphy to get reps to get hot again and then start every game in the post season. We have days off after almost every game, so the idea that we need to alternate catchers in the post season is just stupid. If Snit is an idiot and thinks TD is better, then the irony is TD should start every game in the playoffs. Any catcher alternating in the playoffs with build-in days off would just be moronic. Play the better player every game. I don't think there is a single point in the postseason where we play more than 3 games in a row, and it might even be no more than 2 games in a row
Btw as a reminder, the idea that the FO has nailed postseason playing time decisions might be tainted by our WS. Stupid things we've done just at the top of my head. (1) Dallas Keuchel started two games in a 5 game series and electing to go Fried in relief. Hard to believe we had a 5 game playoff series and proactively gave healthy Soroka + Fried a total of one start! Literally cost us the series. (2) In the WS vs Houston, we randomly benched Soler in game 4 - of course he pinch hit and hit a bomb, but hard to believe we decided to bench him when he was basiclly playing like Super Man since we traded for him. (3) Last year, randomly putting Grissom in when he was clearly not ready for the playoffs. (4) Sticking with Rosario every game when he clearly didn't have it last year, keeping Contreras on the bench for two games last year despite him clearly having been one of our best hitters all season last year. Pretty sure every Braves fan wanted Rosario / Ozuna on the bench last playoffs and they ended up going a combined 0-16 in the series - and this isn't "hindsight" - it was very obvious they did not have "it" last year.
We've done some really dumb stuff on line-up decisions in the playoffs, so I can't say I have full confidence that we "get it right" come playoff time
