Fans and pundits, and sometimes teams, fall into the trap of believing they MUST do it like the current Super Bowl champs did it. For how long has Jerry been trying to duplicate the "triplets" of the early 90's Cowboys' dynasty? The reality is that there are many ways to win a Super Bowl. Because the Chiefs are doing it with Travis Kelce, a lot of teams, fans and pundits are trying to find the next Kelce. But the Chiefs are a whole lot more than Kelce.
Dalton Kincaid is seen by many as the closest approximation in this draft of a Travis Kelce clone. That's why so many fans are lamenting his loss. It's why the Bills moved up to get him. But you are correct. The Cowboys were never interested in Kincaid, or he would have been a 30-visit player. He wasn't.
In the end, the Cowboys got 4 players from their 30 visit players: DT Mazi Smith, LB/S DeMarvion Overshown, DL Viliami Fehoko, and LB/Edge Durrell Johnson - all defensive players.
