Dubas looks to trade back whenever possible early in the draft.
I believe it was in one of Leaf videos on youtube/social media, where Dubas asks the draft table whether they should take the deal, or make the pick, and made the pick because the scouts felt Knies was too good of a player to pass on (which early indications appear to be that is correct)
Not to mention the previous times it happens.
Dubas seems to recognize that the difference between a late first, and an early/mid 2nd is minimal, and takes advantage of it.
Logic we used to get taken to the cleaners with *stares at Brian Burke*
