If Sanchez is being used as the primary DH, then I can sort of but not really but sort of if I squint, look the other way and say we've got 2 catchers and a DH. But, like you, I still don't like that plan. Sano will be DHing, Arraez will be DHing, Kirilloff could be DHing, others could DH when a break is needed on the field, so, Sanchez as the primary DH won't really be primarily a DH and then it's 3 catchers. I've never liked 3 catchers on a roster. It's a wasted space, imo.
But ... I guess we will see. You know me ... none of these decisions are within my control, so while I have my thoughts on the matter, it will be what it will be. And I'll be watching baseball, win or lose. (Well, okay, if there is more of the latter, I will likely be watching less baseball.)
