This. We saw Dak hold the ball for an unprecedented number of sacks this year. Having a tight end who can be a consistent outlet if Prescott isn't comfortable with what he sees downfield is huge.
The other tight ends may be more dynamic than Witten in ability but they do not provide stability. This seems to be undervalued while fans gripe about the fact that Witten isn't a downfield target.
The Cowboys' front office already said tight end was going to be one of its top targets. Now, we're not forced to take one in the second round and can instead give these other ones a chance to show development and try to keep it from being necessary to use Witten more than it sounds like the team plans to. Their challenge is to be better than what Witten provides.
Now, there might have been some better options, but it's no guarantee Dallas was going to sign any of them and drafting one in the second round would have been hit or miss and would have cost us the opportunity to use that pick on another position of need.
