I don't think it was a smokescreen at all. The facts got mixed with some fiction - no team's just going to hand the media their draft board - but it's not like we were completely led astray either.
Dallas' interest in Avila seems genuine. Guard was 1st round consideration. Avila's name may have been a smokescreen, but if you like Bergeron, you probably like Avila too. They're similar types of players.
TE was clearly a priority too, as they reached for Schoonmaker any way you want to slice it.
I am willing to put money down that Kincaid was the Cowboys' #1 target. I have no doubts that they genuinely liked LaPorta, but Kincaid was seen as a better player by every draftnik and their dog. Most likely, they are embarrassed that their building leaked and the Bills used that info to snipe them.
