If you trade down and get 4 picks on day 1 and day 2 that should be 4 starters.
If you trade up to get Hunter you get one player on day 1 and day 2.
Given the state of the Cowboys roster, which move sounds smarter?
I respect the thought process and would agree that this is the more likely route the Cowboys will go, but they key word you used there is "should be" 4 starters. Granted the depth of this draft class is supposed to have increases the odds of hitting on some of those day 2 picks you just dont have very good odds overall. Looking over the last few drafts the Cowboys had in the 1st and 2nd round....
2024 - Guyton & Kneeland - Neither were quality starters year 1, although its too early to declare either a bust
2023 - Mazi & Schoon - Neither have been quality starters yet, both are approaching bust territory
2022 - Tyler Smith & Sam Williams - One plus starter and one solid rotational guy (so far)
2021 - Parsons & Joseph - One major hit and one total bust
2020 - Lamb & Diggs - Two hits
2019 - Non & Hill - Hill was a total bust
2018 - LVE & Williams - Two decent players
2017 - Taco & Awuzie - Taco is an obvious bust - Awuzie has been maybe league average for his career?
Even 1st round picks you see about a 50% bust rate on depending on your definition of a bust, and it only goes up as you get into the 2nd and 3rd rounds. I think its something like only 10% of 3rd round picks will ever make even a pro bowl in their career. I'm certainly not against a trade down to load up on picks, but I wouldnt pass on the opportunity to go get a an elite player either when you have a chance, just because your GM has put you in a position where you really need those day 2 picks to plug in right away.
