If we trade Vaz, Swihart will play more than 30 games. That frightens me, and it should frighten every Sox fan. Look at how our SP'er do when he catches. Maybe, it's just a fluke. Maybe with time, they'd grow accustomed to him and do well. I'm not willing to risk it.
That brings us to Leon, assuming we trade Vaz. My 200 point possibility was based on the assumption that either Vaz or Leon would catch 110-115 games in 2019. Leon seems to tire out the more he plays. He'd probably hit under .500 (yes OPS) if he played that much. I think Vaz can hit near .700 this year over 110-115 games. That's a possible 200 point gain, which is close to the difference between JD and a Pearce/Moreland platoon.
No, I do NOT want to go into the 2019 season counting on Swihart to catch more than 5-10 games. If there's a catcher injury, maybe we could deal with 25-35 starts, but no way do I want a Leon-Swihart tandem all year. I'm not willing to trust the learning curve period is short, or worse, they never adjust to him and our staff ERA jumps a half run or more due to trading Vaz.
Swihart seems to do okay with RP'ers, so keeping 3 catchers and PH'ing for one or two of them in any particular game would minimize the fright level by not seeing Swihart with any of our starters, except maybe ERod, who seems to do about the same with everyone.
Ideally, IMO, Leon starts when Sale & Price do. He only starts with someone else, if Vaz is hurt or needs a rest. Swihart is either a utility player or is traded. (Vaz 110-120 games & Leon 42-52 games started)
I'm going throw a question back at you: why give Swihart a chance? Are you willing to risk our great staff success on these numbers?
Chris Sale:
It's very telling that Swihart has never even caught 1 inning with Sale.

We can gamble that these numbers mean little or nothing, but I'd rather nor.
