The Cowboys front office read it right. TE is a measurables position, and super-athletic receiving TEs like LaPorta are your difference makers in the league.
However, I think the FO galaxy-brained themselves on the Schoonmaker pick. On paper, Schoon has a really impressive bag of tools. Size, speed, explosion, blocking, he's got the whole package. But he never put it together at Michigan, and he had 6 years to try.
He was a boom or bust prospect whose 50 career catches had him leaning towards bust, and he played a low value position, where we already had two pretty good guys in place. Schoon should have been drafted a round later IMO. Now that he's on the Cowboys, Ferguson's emergence is really going to shut him out, unless he lives up to his seam-stretching potential and brings a downfield element that Fergy doesn't.
