Let the NL mess around with that for a while.
The sky didn't fall in the NL when they used the DH this year. They should just use it going forward. Only masochists want to watch pitchers hit.
I would say that it's usually more like trading 4 Canadian quarters for a US dollar. Depending on how the exchange rate fluctuates, you may come out ahead.
Vaz is the only decent fielding Catcher the Sox have. Grullon, Plawecki and Wong are all a little too lackluster behind the dish. Maybe it's not a big deal when robot umps come, but I think Vaz has decent value to the Sox in the meantime.
I think you try to see if he can be a fulltime guy this year. I'd give him a long leash. I know Casas is waiting in the wings, but a productive Dalbec can probably be moved over to 3b or even to a corner OF spot.
I would not be surprised to see Taylor in WOO at the start of the season.
His stuff was greatly diminished last season (likely due to COVID) so he really needs to earn his spot. It's not like his repertoire is amazing, just a run of the mill below average FB/above average Slider. He's basically a left handed Walden.
If they get a glove first CFer, it may make sense to get a bigger bat at 2b than Arroyo. I'm not sure you really want to have 2 black holes in the lineup.
