In case you haven't had a Verizon phone since the Razr Flip phone, every device since said V3 has been rooted and the bootloader unlocked. Save for S4 & S5, which I might add still have root and roms via safestrap. If your only reason for not purchasing a device is a locked bootloader, perhaps you should rethink your actual smartphone needs.
Having a locked bootloader on my S5 doesn't bother me one bit. I sure as hell don't miss flashing buggy roms every other week. Those days are long gone on today's flagship devices.
I certainly wouldn't worry about this Nexus.....afterall.....It's a Nexus, it WIIL be rooted regardless of carrier.
