When a team has a top ten pick in the draft then it typically means that team needs a lot of help. The Cowboys are no different.
There are a lot of uncertainties this year because a lot of these players didn't play a down in 2020. Essentially, NFL teams are drafting seniors and juniors that have only played their junior or sophomore seasons, respectively. These players have far less college experience than all previous drafts.
Drafting a top ten player means putting all your eggs in one basket when it comes to quality players with the potential to play and impact the game. That's a lot of pressure to get the pick right, even under the aforementioned circumstances. Drafting a player never fills a need with certainty, they must transition to the NFL and that usually takes at least one season. Rookies seem to have a higher probability of injury. Good teams typically look to upgrade their overall roster.
The Cowboys must rebuild their defense, both from an executional and talent perspective. with extra picks added to their usual selections, this year in the top third, the Cowboys have a real chance to improve defensive talent. With that said, if the Cowboys have the opportunity to draft a "generational" talent, they should make that pick. It's not going to be Pitts. The first team without a QB need is going to grab him.
