JE was a JUCO transfer who played only one year at the FBS level.
DK was productive in a system for three years at the FBS level, with plenty of playing time given the system throughout those years. I don't really break down film, but I feel he is impressive throughout all aspects of the game when I watch him.
Measurables are borderline, but close enough with hybrid athletes thriving in the NFL recently... including TE position, George Kittle has done quite well.
I'm not saying he's a first rounder, but do think he is someone who will stick around in the NFL for a few years at worst.
