I trust Kupp so little that he looks like a great sell high candidate.
Maybe you misunderstand what that means.

Here are PPR rankings on fantasy pros:


He's rated much higher in half PPR than full PPR. That seems to account for his inflated numbers from 2 of his catches recently. His targets are diminished.
I think his recent fantasy numbers are inflated. I'd be nervous.

In half PPR, he had Adams are listed back to back.
in full PPR, the gap is wider.

I'd widen it even more because I don't trust Kupp.

Is that clearer?
