The intent of my post was simply to point out the "two voices" of N Ray. For Verizon mmWave is bad, for TMUS it's good.
Not sure how often it needs to be repeated until people are no longer surprised by the characteristics of mmW spectrum.
Certainly Sprints 2.5 GHz spectrum is enviable at the moment. C-Band and/or CBRS if and when available will certainly tend to reduce or even eliminate Sprints advantage.
Here’s what Verizon had to say about Millimeter Wave: https://arstechnica.com/information-technology/2019/04/millimeter-wave-5g-isnt-for-widespread-coverage-verizon-admits/
Given all these shortcomings, Sprint should be in the driver’s seat with 2.5 GHz if it could make the appropriate capex happen.
