The part that is more annoying to me is that the argument is being used to basically say "Kupp isn't good and isn't worth trading for". It really seems like there's a sector of Steelers fans who talk down any idea that isn't wildly advantageous for the Steelers.
It's frustrating to watch this team so desperately need WR help only to read some fans saying "we can't overpay for Aiyuk, take a 2nd or we won't trade for him" or "Kupp is too old and injury prone to give up a 3rd" or "Williams sucks, I'd be mad if they traded for him". Like what is it do you want, a prime AB for a 7th round pick?
