You haven't actually provided any evidence to support what you're saying. I provided direct evidence of his defensive impact as well as contextual information.
Your argument boils down to some weird appeal to authority that because he doesn't play Ryan Suter - level minutes, that he clearly isn't good.
You clearly aren't as smart as you said either as you've also demonstrated poor reading comprehension. In my previous reply to you, I never mentioned he should be worth a king's ransom. In fact, I explicitly said the price to acquire is debatable. I took umbrage with your completely misinformed evaluation of his defensive quality, not whatever perceived fair price there would be in a potential trade.
If you think my evaluation of Tanev is wrong, please provide evidence. All you've cited is that he doesn't have an extremely high TOI, and even that, you haven't actually provided any numbers for his average TOI or even-strength TOI.
