Not understanding what you are talking about, you answered your own question
They clearly liked Everett more, or had him higher on their list, or drafted for need yadda yadda they traded back and still got him.
Kupp was the 2nd player they drafted they drafted that year, and he was rated as a mid round pick, So they drafted him ahead of where some folks had him rated.
I dont know what is so complicated about this, if they pick at 26 it will be for a player they want,who they dont think will be available when they pick again in the 3rd round.
