I would say the driving force that got Dak to the Cowboys was about half luck and half coaching/scouting. We were lucky that none of the other teams in the NFL knew about Dak's amazing skill-set. We were lucky we went 4-12 last year, which got out coaches to the Senior Bowl. We were lucky other teams moved up and around to take all of the QBs that were rated as the best pro prospects so Dak was still available when our 4th round comp pick came around.
But, what wasn't luck was actually selecting him with that pick because the Cowboys thought he could have a future in the NFL. All of the other teams had the opportunity to select him and had passed. And it certainly wasn't luck putting the OL together in previous years, cobbling a decent defense together, then drafting Zeke, which helped Dak show the world what he could do coming out of the chute.
