I'm not particularly convinced by this article, but it is an update of sorts:
https://www.mlb.com/news/white-sox-prospect-zack-collins-improving/c-290586256?tid=151437456
I found this part especially annoying (to be clear, I generally like Merk's work fine)
"Any doubts of Collins sticking at catcher have been erased. Just ask pitchers Dylan Cease, Jimmy Lambert, Dane Dunning and Bernardo Flores, all of whom have done high-level work with him."
He proceeds then not to quote or back up that claim at all, as if I actually should just go and ask them ?
