You’re limiting the possible scenarios.
The Cowboys could have valued LaPorta and Kincaid as one tier of receiving TEs and guys like Mayer and Schoonmaker as more traditional TEs on a second tier. That would be consistent with what Archer reported.
It’s clear they valued Mazi and the OL (Bergeron) as higher rated prospects on their board than any of the available TEs, so when both of those guys were available at #26, TE was no longer a consideration. They went with the highest rated prospect at a position of need…Mazi.
When LaPorta went off the board early in R2, they shifted their focus on the remaining tier 2 TE prospects.
