Install newer version of SuperSU, one from play does not install binary to any of NP 12.2 models (if it's still 1.94)
Go HERE and download .zip, unzip it and find Superuser.apk from there and install it. Then try to install binary.
I'm not saying this will work for sure.. but that's how all the others are doing when rooting with towelroot, like me for my international version.
I think it's just the Verizon version that it's not working on.
